I wouldn't exactly call APL simpler than LISP. Just because there are some things in APL that _can_ be coded with less characters doesn't make it overall simpler or even more compact in the general case. It's just axiomatic that for a language you need the ability to define and call functions, and it's just a debate about whether there's a simpler syntax than LISP or not, and I say there isn't.
