Scheme does this. Prolog does it to some extent. The original version of the late Dylan language did this. To what extent is this facility used in XEmacs Lisp? Macros use it, and of course compilers do? What about Perl? -- John McCarthy, Computer Science Department, Stanford, CA 94305 http://www-formal.stanford.edu/jmc/progress/ He who refuses to do arithmetic is doomed to talk nonsense. #:Erik -- ATTENTION, all abducting aliens! you DON'T need to RETURN them!
