Re: [Python-Dev] Classes that claim to be defined in __builtin__ but aren't

The real question seems to be whether __builtin__ should contain *all* built-in types, including internal ones, or only those intended for public use. Do you have an opinion about that, Guido?

I suppose it's reasonable to put them all in __builtin__, since as you say, they can be useful for type checking even if you can't or rarely want to instantiate them yourself.

That's where I stand, at about +0.5. I don't think it's super important that all builtins be particularly well-known or useful -- it's easy enough to have a section in the documentation for "lesser-known builtins". --Guido van Rossum (home page: http://www.python.org/~guido/)
