Re: lexical scope and dynamic extent
In Lucid's SUN Common Lisp 1.0, compiled foo, you get
>>Error: A go to one of (L) occured from within an out of scope closure
Maybe the English needs a little work...

Subject: lexical scope and dynamic extent
Some entities in the language are described as having lexical scope
and dynamic extent, which means that they can be refered to after
they're gone. Do any of the implementations have good ways of
detecting such things? Here's a nasty one:
(defun foo ()
l (return-from foo #'(lambda () (go l)))))
If you type this at various implementations, what do you get?
