On the contrary, using simple names (PEP 550 V1 was actually doing that)
is a regression. It opens up namespace clashing issues. Imagine you
have a variable named "foo", and then some library you import also
decides to use the name "foo", what then? That's one of the reasons why
we do `local = threading.local()` instead of
`threading.set_local("foo", 1)`.
