Yup, that's one of the main problems: when a single let in the source
ends up duplicated after expansion so some expansions may use it while
others end up not using it.

We need to add some way to tell Emacs that it should check "the sum of
all uses" or something like that.  In your case, this "sum" is
open-ended, so we should instead just tell it not to check at all.
