[New-bugs-announce] [issue30162] Add _PyTuple_Empty and make PyTuple_New(0) never failing

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Proposed patch makes the empty tuple be allocated in static memory rather than dynamic memory, expose a reference to it as _PyTuple_Empty, and makes PyTuple_New(0) never raising exceptions. This allows to simplify the code. No longer need to call PyTuple_New(0), check it's result for errors, and clean up it after the use, you just can use a borrowed reference _PyTuple_Empty.

_PyTuple_Empty is for CPython internal use only.
