LISP - yes
Matt
Actually, it's "yes" for Common Lisp, and "no" for Scheme. But there's
a bit more to it than that: Namespaces in Common Lisp map a name
(string) to a symbol, which is the object that holds the name's global
function and/or variable bindings, etc. The add_sub/add_var interface
can be implemented in terms of symbols, though; I'm still digesting the
consequences, but I don't believe it will require anything more of
Parrot.
