Some of that can be done. It may not need specific support. But my intention is to have an ordinary language for everyday coding not one that can only be understood by CS professors.
Mine is unusual in that I can drop features I rarely use, which means that everything in it gets good use. Including multi-level breaks. And the core language can stay small (or smallish - it's not Forth). Which I think is where we came in. -- https://mail.python.org/mailman/listinfo/python-list
