I created a custom dict in a C extension. Name it `promethea`. How can

TypeError: 'type' object is not subscriptable
Somewhere you'll have a table of the class's methods. It needs an entry
like this:
static PyMethodDef customdict_methods[] = {
...
{"__class_getitem__", (PyCFunction)Py_GenericAlias, METH_CLASS |
METH_O | METH_COEXIST, PyDoc_STR("See PEP 585")},
...
};
Note the flags: METH_CLASS says that it's a class method and
METH_COEXIST says that it should use this method instead of the slot.
