@Batuhan Taskaya: would it be worth starting a discussion on either python-ideas or python-dev? (Or on discuss.python.org.)

My concern is that we're discussing a core language change. It's not a major change, but it's not an insignificant one either, and right now the discussion is buried in an issue whose description and "Type" category suggest that it's purely about performance - those giving this issue a casual glance may not realise that there's a language change involved.

I don't have strong opinions on the change itself either way, but others might have.
