About that particular syntax, yes. But not about
the idea of some sort of zipping syntax.

For one thing, it would make it easier to implement
parallel iteration efficiently. When I write

  for x,y in zip(a,b):

I'm just trying to express the way the iteration is
to be carried out. I don't really mean that I want the
zip of the two lists to be computed first and then
iterated over.

If there were a special syntax for zipping, the
compiler could easily recognise this case and
optimise it.

I haven't thought of a syntax for it that I really
like, yet, though.
