Having a dict like d = {'one': 1, 'two': 2} the representation of its keys repr(d.keys()) gives "dict_keys(['one', 'two'])"But since the keys are unique, wouldn't a representation using the set notation be more intuitive, i.e. what about changing the output of dict_keys.__repr__ to"dict_keys({'one', 'two'})" (using curly braces instead of brackets)
From 3.0 to 3.7?, when dict keys were unordered, that might have made sense. But now that dict keys are insertion ordered, I think the list brackets suggesting a significant key order is better. There is also the issue that representation changes can break code and therefore need substantial reason.
