Pattern: __repr__ does not return string

Issue: -

Description

Used when a __repr__ method returns something which is not a string.

Example of incorrect code:

class BadRepr(object):
    """ __repr__ returns bytes """

    def __repr__(self):  # [invalid-repr-returned]
        return b"123"

Example of correct code:

class GoodRepr(object):
    """__repr__ returns <type 'str'>"""

    def __repr__(self):
        return "some repr"
