Not sure. I took a look in svn and only one egg is using the "=" syntax
there, and that's as a functor instantiation in its tests
(levenshtein/trunk/tests/levtst.scm:106). So, you're suggesting that we
make `(module foo = ...)` mean functor instantiation exclusively, and
error when the right hand is just a module? I'm OK with that, especially
since the following is equivalent(?) and arguably more clear anyway:
(module foo-alias ()
(reexport (chicken string)))
Alternatively, we could define a precedence rule, but that may become
confusing quickly and for not much gain.
