Inherit docstring from super class when missing in subclass

[kkom]

Hey! I've got a request similar to #877 but related to class docstrings instead.

See the code below:

class A:
    """
    My docstring.
    """

class B(A): ...

a = A()
b = B()

Here is what Pylance shows on hover for each class:

It would be great if B inherited A's docstring in the absence of its own. Especially as this is the behaviour of inspect.getdoc:

In [1]: import inspect

In [2]: inspect.getdoc(A)
Out[2]: 'My docstring.'

In [3]: inspect.getdoc(B)
Out[3]: 'My docstring.'

I thought we already supported this, but the code path I was thinking of is specifically for inheriting docstrings for overridden methods (which is working). See getFunctionDocStringInherited.. I guess that was the result of #877 which you referenced above.

class A:
    """
    My docstring.
    """
    
    def method(self):
        """
        My method docstring.
        """
        pass

class B(A):
    def method(self):
        pass

a = A()
b = B()

a.method()
b.method()
