Yes, please!

That's enough for me -- will try to integrate.  

As for our implementing our own from scratch, if we do this, it will
have to come from someone else on the team more familiar with lisp, at
least in the near term.  It doesn't appear hard, but I can't justify
the time right now to really dig in and learn lisp.  And the compiler
appears quite efficient, so a hand c implementation also doesn't seem
a wise allocation of time.

If anyone on this list wants to take a crack at implementing some of
these features for gcl in lisp, please feel welcome!

Take care,
