Re: [LONG, off-topic]] Interactive Programming (fwd)
LISP programmers are much more into writing programs which build and execute routines on the fly.
As are some perl programmers. As both a perl programmer and a lisp programer I have never had the need to use self modifing code. In fact I would consider haveing to use s-m code as a sine that I have made a mistate in my desinge.

You eval them. Perl has a construct eval( "string" ) where string can be arbitary perl code which is evaluated into the current context. That can include function definitions even I think.
