interpreters written in maclisp.

[GJC at MIT-MC (George J. Carrette)]

It would be sufficiently nice to have a version of
LEXPR-FUNCALL which took a type-t-array as argument
instead of a LIST. Thus an implementor who knew what
he was doing could save the consing of call frames
without going outside of the language. This is very
much like passing arguments through registers, and
then providing an actual home for them on the stack.
