[New-bugs-announce] [issue32630] Migrate decimal to use PEP 567 context variables

[Yury Selivanov]

New submission from Yury Selivanov <yselivanov at gmail.com>:

PEP 567 allows decimal to be safely used in async/await code.

I couldn't observe any performance impact by the proposed PR.  The PR doesn't modify decimal context behaviour: instead of using a thread-local storage it now uses a context variable.
