Contrary to popular belief, it's actually the comma that creates the
tuple, not the parens...  As an example, I recently copied code from a
dictionary to an assignment a little to hasty:

   foo = {
      'a' : 1,
      'b' : 2,
   }

to:

   a = 1,
   b = 2,

and it took me way to long to figure out where the eventual "unpack
tuple of wrong size" error was coming from... *sigh*   Serves me righ, I
suppose <wink>
