Well, we'd like to replace Emacs's lisp interpreter with Guile, so
there are lots of existing packages which Guile will eventually run
that confound the two.
It's not possible to write a translator that converts code which
assumes nil == #f into code which assumes nil != #f. When the
translator encounters 'nil' in its source, which does it write to its
output?
