[issue14655] traceback module docs should show how to print/fomat an exception object

Amaury Forgeot d'Arc added the comment: Why not reuse format_exception(exc)? in 2.7 you could write "raise type, value, traceback", or "raise value". I suggest that traceback.format_exception take the same route, and accept both (type, value, traceback) and (value). -- nosy: +amaury.fo

[issue14657] Avoid two importlib copies

New submission from Antoine Pitrou : This patch avoids creating a second copy of importlib._bootstrap when a first one exists as _frozen_importlib. This isn't perfect as it mutates the module when importlib is imported for the first time, but I think it's better than the status quo. Also, impor
