The step of "universalizing" function expressions was conflicting with
top-level ascriptions for polymorphic function declarations:
universalization generates universal type variables, and top-level
polymorphic ascription *also* generates universal type variables, and
the two were conflicting with each other when unifying. Let's just get
rid of this now, and we can bring it back in a more principled manner
once we do actual let-generalization (which there's still an ignored
test case for)

Since xanthous has a checked-in package.yaml and cabal file, the
haskellPackages build infrastructure will use the package.yaml file for
all builds. The resulting problem is that our CI won't actually catch build
failures that would be observable with cabal or when building from the
sdist.
We fix that by filtering out the package.yaml file in pkg.nix
additionally to the filters specified in .gitignore. For this we need
gitignoreFilter from gitignore.nix which we expose as part of a functor
set from third_party.gitignoreSource to maintain interface
compatibility.

The following changes in dependencies of xanthous broke the build and
have been fixed in this CL. Thus we can reenable CI for xanthous.
* random 1.2.0 removed the Read instance for StdGen, so we need use
System.Random.Internal to un-newtype StdGen into an SMGen in the
appropriate places as that type still has a Show and Read instance.
Requires a new direct dependency on splitmix as well.
* witherable 4.0 renamed Data.Witherable into Witherable and no longer
exports Filter.
* random 1.2.0 probably also broke the Function instance for GameState
which contains a StdGen. I'm not exactly sure which change exactly
triggered this, but the fix is easy enough: We implement a Function
instance for SMGen using functionShow allowing us to write a Function
instance for StdGen using functionMap. I've put these instances into
Xanthous.Orphans.
* hgeometry 0.12.0.0 removes the triangulationEdges function (which is
also not mentioned in the changelog, so I'm not sure if there's a
replacement yet). Fix by pinning to 0.11.0.0 for now.
* hedgehog-classes: relax bounds on semirings

We make use of the -O man=… option of mandoc(1) which allows to convert
cross references via the .Xr macro into actual hyperlinks in the output.
This can be disabled (by passing "none") or done in two modes:
* all: links all .Xr cross references as if they were in
$out/%N.%S.html. This will lead to broken links of course.
* inManDir: only link to files in $out if the man page is found in
manDir, use the template defined in linkXrFallback if not.
all is the default, since we don't require all man pages to be in
manDir, so it would be potentially confusing if the path attribute was
used in the pages list.
linkXrFallback uses the debian online man viewer by default currently,
since it can be decently hyperlinked and debian has a lot of packages.

What you see here is mostly the fallout of me implementing a correct

(although they'll probably keep it at arm's length).
Where I want to go from here:
* Extend this library towards general purpose nix™, mainly by
implementing missing interfaces which you'd still have to use
<nixpkgs/lib> for right now. Reexposing parts of <nixpkgs/lib>
with better naming is fine for now, at some point I'd contemplate
making this depend on nothing outside of depot, maybe even itself
(should be easy we only use yants for an easily replaceable check).
* Improve error messages possibly by carefully reintroducing yants. I
originally typed essentially everything using yants, but turns out
this can a) be dangerous when stuff you are handling throws because
type checking means evaluating and b) has a incredible performance
cost in some cases.
* Reexpose builtins with better naming and slightly wrapped so they
don't unrecoverably throw in cases where a null or something would
suffice.

* { buildTests = true } doesn't contain anything other derivations want
to depend on, so it is an derivation output we don't want to have.
drvSeqL hides the tests derivation away and only requires us to build
it once.
* Usually drvSeqL has the issue that tests (or advantage) are not rebuilt
if the test derivation changes. This is no question in this case as
due to the embedded nature of Rust's test, both the derivation with
and without tests change anyways regardless of which part was changed.
Future work: Allow injecting other tests?

In order to store a function in the interpreter's representation of a
callable, the lifetimes used throughout rlox need to be threaded
through properly.
This is currently not optimal, for two reasons:
* following the design of the book's scanner, the source code slice
needs to still be available at runtime. Rust makes this explicit,
but it seems unnecessary.
* the interpreter's lifetime is now bounded to be smaller than the
source's, which means that the REPL no longer persists state between
evaluations
Both of these can be fixed eventually by diverging the scanner from
the book slightly, but right now that's not my priority.

some kind of weird Nix->OLC mapping that is mostly undocumented.
This moves the config we need to the new format in a way that may or

decided to impose on us. Note that this now throws lots of warnings,
but I can't be bothered to fix them.
* 3p: Random package removals accomodated
* users/glittershark: Pin grfn's kernel to 5.9, because the CK patch
is not yet updated for 5.10
* users/glittershark: Update vendor hash for pg-dump-upsert, I suspect
this changed because of something in the Go build machinery in

* users/glittershark: agda build is broken, commenting out development

* third_party/haskell_overlay: updating random needs upper boundarles

The "swap-window" command swaps two windows, the 'source' and
'destination' window, exchanging the indices they occupy in the window
list. In at least tmux 2.8 (which is what's in Debian Stable), if the
window under focus is the source window, then focus follows that window
(i.e. the focus changes to the current window's new index atomically
with it being moved to that index).
In more recent tmux versions, this is not the case, and the focus
remains on the old index, so that the replacement window comes under
focus. The former behaviour is still possible, but must be explicitly
requested.

This adds my standard inputrc to my home-manager configuration, via the
latter's readline module, and adds nix-shell detection to my bash prompt
string.
Additionally, nix-shell is wrapped in a shell function, so that entering
a nix-shell environment automatically runs bash as a subprocess where
appropriate, as the default environment spawned by nix-shell is not to
my liking.

... still not that interesting, but at this point slightly divergent
from the book:
The book embraces mutability for interpreter state, initially for
tracking whether an error condition has occured.
I avoid this by instead defining an error type and collecting the
error values, to be handled later on.
Notes: So far nothing special, but this is just the beginning of the
book. I like the style it is written in and it has pointed to some
interesting resources, such as a 1965 paper titled "The Next 700
Languages".
