[Python-Dev] Classes that claim to be defined in builtin but aren't (original) (raw)

Guido:

But list and dict are not functions, they are types, and they can be used for subclassing and type checking too. These are the precedent for placing generator etc. in builtin.

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.
