[issue31563] Change repr of dict_keys, dict_values, and dict_items to use curly braces

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I concur with Raymond.

As for supporting the full set() API I thought about making unbound method set.union() and friends accepting arbitrary Set objects (or even arbitrary iterables), not just set objects, as a first argument. But I didn't investigate how this will affect the performance of the set objects.
