Instance variable docstrings are lost if the variable is redefined

[mikecharles]

It appears that when an instance variable is redefined below its original definition (which includes the docstring), then the docstring gets lost.

For example:

class Test:
    def __init__(self, name=None):
        self.name = 'Mike'
        '''Name of person'''
        self.age = 30
        '''Age of person'''
        self.gender = None
        '''Gender of person'''

produces:

while this:

class Test:
    def __init__(self, name=None):
        self.name = 'Mike'
        '''Name of person'''
        self.age = 30
        '''Age of person'''
        self.gender = None
        '''Gender of person'''

        self.name = name
        self.gender = 'Male'

produces:

Shouldn't the docstring be locked down once it's found (unless another attached docstring is found)?
