PEP 695 – Type Parameter Syntax
sunmy2019 commentedon Apr 24, 2023
Wow. This syntax looks so cool. It reminds me of many generic expressions in other languages, such as C++ and Rust. (while the increases the learning curve of Python)
I'll see what I can help here.

I feel we should defend the intuitive readability of python irrespective of what.

@JelleZijlstra - I'm sorry if this is the wrong place to ask, but is the specification and implementation of PEP 695 sufficiently stabilized that I could look into updating Ruff's parser and semantic model to support them?
JelleZijlstra commentedon Jun 22, 2023
I don't expect more major changes, no. There are currently no open PEP 695-related bugs; if anything else changes it would be as a result of new feedback we receive during the beta phase.
