LISP does that too, lest anyone forget, as well as some variants of LPC, the
programming language that powers some kinds of MUDs and the Roxen httpd.
The Amylaar version specifically has a structure called a "closure" that
can be written up by the routine on the fly. And, in the totally obscure
category, an old COMPUTE!'s Gazette utility called "Smart VAL" lets the VAL()
function on Commodore 64 BASIC 2.0 act identically to the example above.
