Erk. This is not how I envisaged context vars would be
used. What I thought you would do is this:
my_context_var = ContextVar()
def foo():
my_context_var.set(1)
This problem would also not arise if context vars
simply had names instead of being magic key objects:
def foo():
contextvars.set("mymodule.myvar", 1)
That's another thing I think would be an improvement,
but it's orthogonal to what we're talking about here
and would be best discussed separately.
