Dot-comma, anyone? (Re: zip or marry etc)

In that case, obviously the solution is to combine this
thread with the one on new operator symbols, and define
an elementwise tuple-creation operator

   .,

as in

  [1,2,3] ., [4,5,6] == [(1,4), (2,5), (3,6)]

It might even look halfway decent in a for loop:

  for x,y in a.,b:
    ...

It would be a somewhat strange operator, as it would have
to extend over multiple arguments like comma does, so that

  for x,y,z in a.,b.,c:
   ....

would do the right thing. So it wouldn't really be an operator,
more of a new built-in syntax for zipping, in the same way
that the comma is a built-in syntax for tuple construction.
