I don't disagree that more intro docs are needed.

However, just to cut short a fruitless discussion, there is zero chance
that Python will change (nor is there any chance that the other languages
will change). Language features that look the same often don't behave the
same (e.g. variables in Python are entirely different beasts than in C#,
and also behave quite differently from variables in JavaScript). Also, if
you aren't giving up on changing Python, please move to python-ideas, which
is the designated place to discuss possible language changes.
