Summary

Hi,
possible linter check - method wrapped to property decorator must have at least one explicit return, possible issue is:

In [1]: class A:
   ...:     @property
   ...:     def b(self):
   ...:         "Hi"
   ...: 

In [3]: A().b is None
Out[3]: True

of course it should be covered by tests, but sometimes is not, especially if it's some special path in the code.
