Python 3 addressed this issue (w.r.t Python 2) in a similar way, using dict_[keys|values] objects. It is common in that language to manipulate the dict_keys. As they are set-like structures, it allows to efficiently manipulate the keys of a dictionary prior to its access/modification. The proposal doesn’t elaborate on the use of I feel like the proposal’s Dictionary.Keys could benefit from a similar approach, not limiting itself to conforming to Collection. > How much effort did you put into your review?
