If by "this" you mean adding to stdlib something like 

@record

class Point:

    x: int

    y: int

or something along the lines of my "modifiers" proposal (https://mail.python.org/pipermail//python-ideas/2016-September/042360.html), then I think I would like to help writing such a PEP. But I thought these proposals were rejected.
