I mean couldnt you say that about any language?
Looks at a standardised language like common lisp
The language itself has been locked for decades, but you've got libraries and compiler instructions that add features like OOP, strict typing, async, etc.
Long live the macro!
There's lots of stuff written in python today that's obsoleted by stuff in the 3.13 alpha
Didn't rust base a lot of its marketing on the promise that there will never be a rust 2, and that all code will be backwards compatible?
