[Python-Dev] When does `PyType_Type.tp_alloc get assigned to PyType_GenericAlloc ?

2016-02-07 Thread Randy Eels
Hi everyone, I've a question about the implementation of the `type` builtin (in Python 3.5). In Objects/typeobject.c, the `tp_alloc` slot of PyType_Type gets set to 0. However, I can see (using gdb) that it later gets assigned to `_GenericAlloc`. I'd argue that this makes sense because, in

Awesome, I missed that. Thank you Brett. Am I understanding correctly that if I'd like to avoid `async with await EXPR` whatever is returned from EXPR must implement `__await__` as a non-coroutine method? Which then I'd just be able to use `async with ...`? 2016-02-06 16:05 GMT-06:00 Brett
