I am currently working on an OO database engine for a MUD. I have
decided to use xlisp for this (I need OO more than database stuff).

I have a couple of questions though.

	1) Why does xset() call setvalue(), while xsetq() calls
	   xlsetvalue() to do it's work? As things stand at the
	   moment, set will only set the global value of a symbol.

	2) Why doesn't xlobget/setvalue search the ivars of the object
	   being sent the message, when looking for local bindings of
	   symbols? Why should it? I wanted to hack things for my OO
	   system. The way I have done it is to check the ivars of the
	   recieving object after the other ivars & cvars have been
	   checked. This means I may scope out a global symbol from a
	   method if a child class has an ivar with the same name, but
	   at least I won't scope out an ivar or cvar that used to be
	   in scope.

p.s. I know #2 isn't all that wonderfull, but it does let you hack
things, particularly with #1.
p.p.s I am an xlisp neophyte, but I am very good at C.
