Let's hold this thought, OK?  I would rather add the tests when you
have a patch to fix them.  Alternatively PRs could be filed and the new
tests KFAILd, but I don't think that adds much value.

What's the problem with parsing (:exp)?  An exp can't be empty, and a
colon can't appear at the start of an exp.  I don't think (exp:) will
be any harder but my yacc is rusty.
