@ -55,7 +55,9 @@ optimisations, but note the most important ones here.
When accessing identifiers like `builtins.foo`, the compiler should
not go through the trouble of setting up the attribute set on the
stack and accessing `foo` from it if it knows that the scope for
`builtins` is unpoisoned.
`builtins` is unpoisoned. The same optimisation can also be done
for the other set operations like `builtins ? foo` and
`builtins.foo or alternative-implementation`.
The same thing goes for resolving `with builtins;`, which should
definitely resolve statically.
