These are arguably very closely related languages, so it's a kind of
"best case" scenario.  And even in that scenario, there are significant
dark corners.

Of course, you can learn to program in "Emacs Scheme" fairly quickly
if you're familiar with Scheme, but it's not quite like programming
in Scheme.  And the docstrings can't be trusted because they point you
to Elisp macros you can't use.  And ...

Now, think about what would happen when trying to interoperate with JS,
Python, younameit, ...
