Hello!
In order to explain, let define subclass of dict:
class Pair:
def __init__(self, key, val):
self.key = key
self.val = val
class MyDict(dict):

def __init__(self, *args, **kwds):
if len(args) > 1:

Yes... But I expected that dict constructor will use `__getitem__` or
`items` method of MyDict instance in order to retrieve items of the MyDict
instance during construction of the dict instance... Instead it interpreted
MyDict instance as the dict instance during construction of new dict.This

So in such cases it should not subclassed `dict`, but
`collections.MutableMapping`, for example?
