Time for Python 4.0

[Eclips4]

Feature or enhancement

Proposal:

Hello dear Python users and developers,

I propose that we release a new major Python version: Python 4.0.

Pros:

• Allows us (CPython developers) to break literally everything with no regrets.
• print() will become a statement again, because nostalgia matters.
• Walrus operator (:=) will be replaced with a real walrus emoji (🦦=) for improved readability.
• len() will now be a method on all sequences, because "everything is an object."

Cons:

• Users might complain.
• Guido might come back just to stop us.

Thoughts? Suggestions? Should we skip straight to Python 5? 🚀🐍

Spoiler ⚠

April Fools! There is no new syntax. Keep using indentation.

Rewrite it in Rust while at it!

It would be great to return to 2.x codebase for Python 4.0.
It may be even better to introduce an imaginary versioning schema for this great project - Python 4.0i or Python 4.0+i, where i=sqrt(-1).

Thank you for your great suggestion. I love 1 April 🎉

But now it is time to close it :(

@sobolevn: You beat me to it! Out of respect, I was going to wait until it wasn't April 1 AOE (Anywhere On Earth), which was a few minutes ago!
