And that's indeed the problem; if an object has __call defined, then
it will use that.  If __iter is defined, that would be tried first.

So we would get a clear notation for objects which are 'list-like' and
define __iter as a iterator constructor.

for x in obj do: print(x) end

Python envy?  We should be not too afraid of what Python does; I think.

This is something that would give 5.3 a definite increase in expressiveness...
