I am interested in "alternative" computer languages, and the ICON computer
language has structures such as are being talked about here, for a general
pick (nth) operator, the exact syntax of <expr>(x1,x2...xn) is used.
<expr> can be an integer constant, an arithmetic expression, the name of
a function in which case the function will be called with all the xi's as
arguments.  One can also use &'s instead of commas in which case expression
failure of an xi causes failure of the rest of the expressions and evaluation
halts there.  All three <expr> types are handled uniformly, (ICON is written
in C) they all pass through the same C code since something like
2(a,b,c) can be looked at as a function named "2" that returns its second
argument, (but all of them get evaluated anyway).

To program is human, to debug is something best left to the gods.
"Spitbol?? You program in a language called Spitbol?"
  The reason computer chips are so small is that computers don't eat much.
