OK, then it definitely sounds like gentemp would be more appropriate
(at least according to the Common Lisp definitions).  I suggest that
we go ahead and make gensym produce uninterned symbols and gentemp
produce interned symbols.  Might be worth looking at CLtL2, and where
there's no reason not to, match their behavior.

Ahh.  I figured that a "solution" would need to look something like that.
