Algol68 doesn't quite have first-class functions. You are not allowed to
export a function out of the extent of the block that declared it,
*especially* if it references locals of the outer block, i.e., the
interesting and useful case.

Ones that do have proper first-class functions include Scheme, Common
Lisp, ML (and any pure functional language worth mentioning), and Pop11.
If you're interested, I can describe how Pop11 does its first-class
functions; I won't burden the whole Net unless I get overwhelmed by
requests.
