Comment (by gridaphobe):
To clarify, there are two kinds of rewriting that happen with `assert`.
1. Adding the source location.
2. Eliminating the assertion from "production" code.
(1) is possible with implicit CallStacks, and is already done that way,
(2) is a separate issue for which we don't have a more principled
mechanism.
But maybe we do, what about a rewrite rule? Those only fire when
optimizations are enabled.
