I would assume that most of the popular high-order functions came from the lisp world; 16 year web devs are using Javascript which took more than a bit of inspiration from the lisps. That said, to really squeeze the most out of HOFs the language probably needs a well developed type system. I've noticed with untyped code that at some point HOFs start becoming hard to write because the layers of abstraction get confusing in a way that static analysis would be helpful with. Although my lesson there is to not go overboard with HOFs - if I need static analysis to write working code it is probably too clever to understand by reading it! The Haskell community might succeed in proving that view wrong, but until then...
