Now I may be demonstrating a certain amount of historical ignorance
here, but I was under the impression that Lisp-2 referred to the fact
that there were effectively to different *name* spaces, one in which
'ordinary' values were bound and one in which 'callable' values were
bound. However, this text:

Makes it sound  like there are two fundamentally different *types* of
values And FUNCALL and FUNCTION are the type cast operators between
those types. Is this a valid way of looking at this?
