This one necessarily has to diverge more from the book than the

I'm happy with the rough shape.
Since we're reusing the old scanner, the compiler/parser struct owns
an iterator over all tokens with which the pull-scanner from the

When a file is added to the depot tree that is picked up by read-tree,
but it’s not a function like ({...}: {}), `readTree` will fail on the
function application, leading to a bad error message.
We can do slightly better, by checking the type and throwing a nicer
trace message.
`assertMsg` is copied from `nixpkgs/lib/assert.nix`, since at this
point we don’t have a reference to the lib.
There is another evaluation failure that can happen, which is when the
function we try to call does not have dots; however, nix does not
provide any inflection capabilies for checking whether a function
attrset is open (`builtins.functionArgs` only tells us the attrs it
mentions explicitly). Maybe the locality of the error could be
improved somehow.

Previously, for types defined using typedef (like all primitive types)
type.checkType would return a boolean. This is largely fine since in
most places `type.checkToBool (type.checkType x)` or similar is used.
However, some functions actually take type.checkType up on the promise
that it returns a set of the form:
{
ok = <bool>;
err = <option string>;
}
This is the case for restrict which has checkToBool = v: v.ok; and will
generate a proper set except if `t.checkToBool (t.checkType v) == false`
in which case it will return t.checkType v. If t was a primitive type or
defined using typedef, previously `t.checkType v` would be a boolean
which meant as soon as (restrict …).checkToBool was called on a restrict
checkType result in cases where the wrapped type didn't match, an
unrelated error would be thrown:
nix-repl> with nix.yants; restrict "foo" (_: true) int "lol"
error: value is a boolean while a set was expected, at /home/lukas/src/depot/nix/yants/default.nix:38:39
This is fixed by making typedef return a proper set from checkType and
adjusting its checkToBool accordingly.
Unfortunately I don't think we can easily add test cases for this except
by using recursive nix or VM tests as there is no way to introspect
error messages.

Things done to resolve upstream breakages:
* grpc no longer takes abseil-cpp as an input, it has also been removed
in the override.
* Upgrade glittershark's kernel to 5.11 since the linuxPackages_5_9
attribute has been removed by upstream and the patch used by them is
available for 5.11 as well.
* The fixed output hash for third_patry.apereo-cas changed for some reason.
* Remove the pin of haskellPackages.vector from the haskell overlay. It
broke as the most recent version of vector in nixos-unstable no longer
depends on semigroups. This effectively updates vector from 0.12.1.2
to 0.12.2.0.
* Align two comments in tvix/libstore/worker-protocol.hh because the
updated clang-format now demands that.

Nix unfortunately has terrible escaping syntax: If something is an
escape sequence it does not know, like \0, it just swallows the
backslash and returns the second character (byte) as is (yes,
"\0" == "0" is true). This created the following bug in nixFileName
which should have resulted in at least a parse error: "(.*)\.nix" is
the same as "(.*).nix" which meant that nixFileName matched anything
that is at least 4 characters long and ends in "nix". This lead to
readTree creating double attributes when directories are involved or
attributes for non-nix files.

testRustSimple is intended to wrap rustSimpleLib and rustSimpleBin and
theoretically pkgs.buildRustCrate with { buildTests = false; } while
building and running their tests, making them fail if the tests don't
succeed.
This is implemented using nix.drvSeqL which is a perfect fit here:
* { buildTests = true; } only returns an output with the test binaries
and does not actually run the tests. With drvSeqL we can easily wrap
this derivation.
* { 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?
