Thanks for pointing out, where it comes from, Serhiy.
So, should the test case be removed then. I still am not so sure about
the bug nature.
Because using the standard mechanism will do this:
x : int
class C:
del __annotations__
x : float
y : int
print(__annotations__)
This will give float for x, and int for y, both of which are wrong for the module.
I do agree that "del" on "__annotations__" might not have a use case, or does it? I think
it's optimized away if not used for classes anyway, isn't it?
Maybe you want make "del" on __annotations__ a syntax error then?
Yours,
Kay
