> If we extend PyType_GetSlot() to accept non-heaptype, we need find a way to judge the max slot of non-heaptype.

Static types can have some sub-slots structs but not others. A "max slot" will not help for types that have tp_as_mapping but not tp_as_number, for example.
You'll probably need some table like typeslots.inc to record which sub-slots struct each slot belongs to.
