So one doesn't have to say?

for v in myobject:myiterator() do print(v) end

This seems a wee bit odd, to make a core change so that we save two
characters and end up confusing people anyway.

Currently obj:method has no meaning without the parentheses.  There
has been a proposal from Mark Hamburg that it should mean a closure
that works like this:

function (...)
  return obj:method(...)

This would be a useful shortcut for functional styles where you would
be passing functions for 'bulk' operations on tables, although again
there are possibilities for confusion which may make this not
