But i think this is more than a minor problem. This is a namespace collision problem, and that's significant. Naming the method "next" means that any object with a "next" method cannot be adapted to support the iterator protocol. Unfortunately "next" is a pretty common word and it's quite possible that such a method name is already in use.
Can you explain this? Last time I checked CVS, PEP 246 wasn't implemented yet, so I don't think you mean "adapted" in that sense. Generally speaking, iterator implementations aren't created by making changes to an existing class -- they're created by creating new a class. The only change to *existing* classes needed is the addition of an __iter__ method to the underlying container object. So I'm not sure what you mean.
