Quoting Armin Ronacher: By far my biggest problem with the language is the stupid slot system. I do not mean the __slots__ but the internal type slots for special methods. http://lucumr.pocoo.org/2014/8/16/the-python-i-would-like-to-see/ Armin shows the history of these "slots" (or however they're called) back to Python in 1990! static number_methods int_as_number = { intadd, /*tp_add*/ intsub, /*tp_subtract*/ intmul, /*tp_multiply*/ ... etc I don't know where the name "slot" comes for from the various tp_* members (fields? attributes? slots?) but I'm pretty sure I've heard it before. I don't normally pay attention to what happens in the C implementation, but I'm fairly sure he's referring to these tp_* thingies. Oh yes, here you go: https://docs.python.org/2/extending/newtypes.html#type-methods refers to "tp_* slot" regularly. What does "tp" stand for? Type something, I guess. -- Steve _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
