Currently, @typing.final is implemented as an identity function, which makes it impossible for type checkers that look at runtime objects to support it.
I propose that we implement it as something like:
def final(f):
try:
f.__final__ = True
except AttributeError:
pass # in case it is used on an object that doesn't support setting attributes
return f
I will submit a PR implementing this idea.
