Ah. I missed that, as I've only noticed this newer thread. And I

must be really good.
It works :)
So does GOTO.
What is the problem with GOTO? GOTO is used extremely effectively
throughout the Python C source code. I've yet to hear of anybody say
never use it.
Seriously, though, how is
1) Do {this} forever, until something happens that I'll tell you about later
better than
2) Do {this} until this condition, which I'm telling you about RIGHT
NOW, changes
?
Granted, this can all be clarified with good comments - but the second
approach basically documents itself.
So what, to me this is a trivial issue compared to many other problems
that can easily be solved in Python that can only be solved in other
languages by jumping through hoops, with the Factory pattern springing
instantly to my mind.
