[§ 3.10] those best bound rvalue references, so auto && wtf = &q; becomes rvalue reference ( && , && stays && ) type of &q . isn't int , it's int * . that'

in python, if copy list or dictionary, copied instance equal original: >>> = [1, 2, 3] >>> b = copy.copy(a) >>> == b true >>> = {"a":1, "b":2} >>> b = copy.copy(a) >>> == b true but if copy object, result not equal original: >>> class myclass(): ... def __init__(self, name): ... self._name= name ... >>> = myclass('a') >>> b = copy.copy(a) >>> == b false why? equality in python objects checked calling __eq__() function. example: >>> class ca: ... def __eq__(self, other): ... print("equals") ... return true ... >>> c = ca() >>> b = ca() >>> c == b equals true that because list equality dependent on elements , not actual memory location (reference) list stored, is, can 2 different list references, if have same elements in same order, lists equal. example
