I just wanted to make a remark about compiled and interpreted functions. I 
will reproduce this message later in comp.lang.lisp, once google catches up 
on the #'(lambda ()...) thread.

	(COMPILED-FUNCTION-P function-object)
returns ALWAYS true. This is so because the purpose of COMPILED-FUNCTION-P is 
to reveal whether the function object may change at runtime and all function 
objects are either compiled to bytecodes or to machine code. Thus, no 
function object has run-time dependencies (no macros are expanded, no 
load-time values have to be evaluated).

There was a bug in the printer however. This bug lead to
	(PRINT bytecodes-object) => #<Interpreted-function ....>
This bug has been fixed today in the NEW_COMPILER branch of the CVS tree.

Best regards,
