Description
Overloaded staticmethod isn't considered correctly by the type checker.
foobar.py
from typing import overload
class Snafu(object):
@overload
@staticmethod
def snafu(value: None) -> None: ...
@overload
@staticmethod
def snafu(value: bytes) -> bytes: ...
@overload
@staticmethod
def snafu(value: str) -> bytes: ...
@staticmethod
def snafu(value):
return bytes(value, encoding='UTF-16')
print(Snafu().snafu('123'))
While running mypy foobar.py expected output: Success: no issues found in 1 source file,
but got foobar.py:21: error: No overload variant of "snafu" of "Snafu" matches argument type "str" .
I guessed #5224 had to fix this, but i've got the behavior above.
Am i doing something wrong?
mypy v0.740, Python v3.7.4
