An optional feature I had in mind was conditional compilation, so that
users should decide at build time which version they want.  But the
names and signatures of the functions exposed to Lisp should be the
same in both cases, so that Lisp programmers don't need to change
their programs to cater to both alternatives.

Apologies if what I wrote was not clear enough about that.  For the
future, I suggest that we discuss the practical implication of
significant changes before you go ahead and invest many hours in
implementing and testing them.  I would like to avoid situations where
you invest significant efforts based on misunderstandings.

Thanks.
