Subject: Re: What's the point of flet?

You may simply need a better Common Lisp environment. Suppose you have this silly function: (defun foo () (flet ((bar () t)) (bar))) In Allegro CL, this defines two functions reachable with fdefinition: one named by the symbol foo, and one named by the list (flet foo bar). That is, #'(flet foo bar) returns the inner function bar. If this is not a closure, it is funcallable. (funcall #'(flet foo bar)) => t You can trace inner functions and use these function names in a number of interesting places. I think this is a very useful and intelligent extension to the function name concept, given that it has to be supported for setf methods. /// -- Norway is now run by a priest from the fundamentalist Christian People's Party, the fifth largest party representing one eighth of the electorate. -- Carrying a Swiss Army pocket knife in Oslo, Norway, is a criminal offense.
