Scope hinting is simply called braces; `from __future__ import braces`.

IMO assuming all things are equal seems to miss how things actually are. The pluses still fall on Python some times, and other languages at other times. Things do vary; developer availability, library availability, target system support, certification story, tooling, even curbside appeal can be legitimate on some occasions.
I'm trying not to pick on your individual language examples, as firing digs seems to be missing the point we're discussing. Or perhaps it is the very point, as two of them wouldn't have even been in my list.
