This particular feature was introduced into the
PL arena by SETL I suppose?

Nowadays it is everywhere, nearly all functional
languages have it. Python has it too.

For languages which have decent support for
macros, Lisp & Scheme on one hand, and
camlp4 on the other hand, this is really a 
small thing.

Conceptually, every mathematician knows it and 
uses it.

I can't say this tells much about the strength of
Smalltalk or Squeak, or Ruby.
