The reason I'd like the construct is because it's explicit - intent (and the scope/limit of your intent) is encoded in what you create. It's clear you intend to do nothing with that name except symlink to the nested member, so the reader doesn't have to anticipate other behaviour (and can't accidentally do something else with it). Generic assignment doesn't convey the same restricted intent, and it doesn't carry those guard rails.

Really though it's a structure that only makes sense in strongly typed languages, so I probably shouldn't have used Python to illustrate the idea.
