Why not the same interface as thread-local storage? This has been the question which bothered me from the beginning of PEP550. I don't understand what inventing a new way of access buys us here.
This was covered at length in these threads: https://mail.python.org/pipermail/python-ideas/2017-August/046888.html https://mail.python.org/pipermail/python-ideas/2017-August/046889.html FWIW, it would still be nice to have a simple replacement for the following under PEP 550: class Context(threading.local): ... Transitioning from there to PEP 550 is non-trivial.
And it should not be trivial, as the PEP 550 semantics is different from TLS. Using PEP 550 instead of TLS should be carefully evaluated.
