[Python-Dev] Make class_getitem a class method (original) (raw)

Shouldn't we optimize the usability for pure-Python first, and then for C API?

Right now we have the 'new' magic method, which isn't a @classmethod. Making 'class_getitem' a @classmethod will confuse regular Python users. For example:

class Foo: def new(cls, ...): pass

  @classmethod
  def __class_getitem__(cls, item): pass

To me it makes sense that type methods that are supposed to be called on type by the Python interpreter don't need the classmethod decorator.

METH_STATIC is a public working API, and in my opinion it's totally fine if we use it. It's not even hard to use it, it's just mildly inconvenient at most.
