Hi,
when running a code analysis in PyDev 3.8.0, I noticed that
- using 'cls' instead of 'self' as the name of the first parameter of a
metaclass instance method is flagged as an error (but see example in PEP
3115)
- metaclass instance methods are not always recognized as attributes of
instances of the metaclass. Calling such method for an imported class is
flagged as an error
Here is minimal example:
meta_ca1.py:
class MyMeta(type):
def create_instance(cls): # flagged as error
return 42
class MyClass(metaclass=MyMeta):
pass
print(MyClass.create_instance()) # not flagged as error
meta_ca2.py
from .meta_ca2 import MyClass
print(MyClass.create_instance()) # flagged as error
Am I missing something?
