alt Hacker NewsIn Python attribute access aren't stable! `self.x` where `x` is a property is not guaranteed to refer to the same thing.
And getting rid of descriptors would be a _fundamental change to the language_. An immeense one. Loads of features are built off of descriptors or descriptor-like things.
And what you're complaining about is also not true in Javascript world either... I believe you can build descriptor-like things in JS now as well.
_But_ if you want that you can use stuff like mypyc + annotations to get that for you. There are tools that let you get to where you want. Just not out of the box because Python isn't that language.
Remember, this is a scripting language, not a compiled language. Every optimization for things you talk about would be paid on program load (you have pyc stuff but still..)
Gotta show up with proof that what you're saying is verifiable and works well. Up until ~6 or 7 years ago CPython had a concept of being easy to onboard onto. Dataflow analyses make the codebase harder to deal with.
Having said all of that.... would be nice to just inline RPython-y code and have it all work nicely. I don't need it on everything and proving safety is probably non-trivial but I feel like we've got to be closer to doing this than in the past.
I ... think in theory the JIT can solve for that too. In theory

This is the fundamental issue and "elephant in the room" that everyone is seems to be overlooking, and putting under the carpet.
The extreme compiled type language guys going gung-ho with very slow to compile and complicated Rust (moreso than C++), while the rest of the world gladly hacking their shiny ML/AI codes in scripting language aka Python "the glue duct tapes language" with most if not all the fast engine libraries (e.g PyTorch) written in unsafe C/C++.
The problem is that Python was meant for scripting not properly designed software system engineering. After all it's based on ABC language for beginners with an asterisk attached "intended for teaching or prototyping, but not as a systems-programming language" [1].
In ten years time people will most probably look in horror at their python software stacks tech debt that they have to maintain for the business continuity. Or for their own sanity, they will rewrite the entire things in much more stable with fast development and compiled modern language eco-system like D language with native engine libraries, and seamless integration C, and C++ (to some extend) if necessary.
