New submission from Serhiy Storchaka:
The repr of subclasses of some collection classes contains a name of the
subclass:
>>> class S(set): pass
...
>>> S([1, 2, 3])
S({1, 2, 3})
>>> import collections
>>> class OD(collections.OrderedDict): pass
...
>>> OD({1: 2})
OD([(1, 2)])
>>> class C(collections.Counter): pass
...
>>> C('senselessness')
C({'s': 6, 'e': 4, 'n': 2, 'l': 1})
But the repr of subclasses of some collection classes contains a name of the
base class:
>>> class BA(bytearray): pass
...
>>> BA([1, 2, 3])
bytearray(b'\x01\x02\x03')
>>> class D(collections.deque): pass
...
>>> D([1, 2, 3])
deque([1, 2, 3])
>>> class DD(collections.defaultdict): pass
...
>>> DD(int, {1: 2})
defaultdict(<class 'int'>, {1: 2})
Shouldn't a name of the subclass always be used?
