Hmm, I just reverted to the previous code without actually thinking
about it. But after checking this more closely, I find that passing
non-nil LEXICAL to `eval' doesn't really do anything for compiled
functions anyway: the "lexicalness" has already been applied when
compiling. E.g., the above change has no effect on the attached tests.
