[issue37210] Pure Python pickle module should not depend on _pickle.PickleBuffer

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Right, it is probably not possible to write a pure Python PickleBuffer. There's a reason it's written in C...

When you said "make PickleBuffer an optional dependency", I thought you intended to have a usable pure Python Pickler, but without support for the PickleBuffer class.
