Strange.

I'm going to have to disagree with the BFDL here. Tuple parameters are probably not used much because people don't know about them, not because they're unhelpful. And all the code transformations he shows below end up longer. And they don't seem to be any easier to read. :-/

Consider what PG says in the arc tutorial.

"Since functions of one argument are so often used in Lisp programs, Arc has a special notation for them. [... _ ...] is an abbreviation for (fn (_) (... _ ...)). So our first map example could have been written

  arc> (map [+ _ 10] '(1 2 3))
  (11 12 13)

Removing variables is a particularly good way to make programs shorter. An unnecessary variable increases the conceptual load of a program by more than just what it adds to the length."

It's strange that this would be what pushes me over the fence, but I think Python and I are going to end up parting ways...
