I'm aware of this python/mypy#6710

I understand the points raised here python/mypy#6710

However the current issue is that

raise NotImplemented()

seems perfectly valid to mypy when in fact it isn't, since it's not callable.

So basically, it should have been a NotImplementedError but mypy didn't find it (I found it with pyflakes).

Do you think it is possible to make it an almost-but-non-callable-Any?

Otherwise it could perhaps be mypy to warn about odd uses?
