This is fixed by introducing a “per-module gensym” (patch attached; to
be applied on top of the previous one).  That way, the sequence number
in generated identifiers only depends on the module being compiled, not
on whether other modules are being interpreted or not.

The ‘module-gensym’ procedure I added adds a hash of the module name in
the identifier, to distinguish from symbols introduced by ‘gensym’.
This makes symbols 3–4 characters longer; perhaps we could avoid it.

Thoughts?

Thanks,
