I've always thought the flexibility should allow python to consume things like gRPC proto files or OpenAPI docs and auto-generate the classes/methods at runtime as opposed to using codegen tools. But as far as I know, there aren't any libraries out there actually doing that.
replyGenerating code at runtime is often an anti-goal because you can’t easily introspect it. “Build-time” generation gives you that, but print often choose to go further and check the generated code to source control to be able to see the change history.
replyBut it's an fairly easy build if you want any of that.
replyThere are some use cases for very dynamic code, like ORMs; with descriptors you can add attributes + behavior at runtime and it's quite useful.
Anyways, breaking metaprogramming and more dynamic features would mean python 4 and we know how 2 -> 3 went. I also don't think it's where the core developers are going. Also also, there are other things I'd change before going after monkey patching like some scoping rules, mutable defaults in function attributes, better async ergonomics, etc.
replyI've used a library that patches the zipfile module to add support for zstd compression in zipfiles.
replyIn python3.14 the support is there, but 2 years ago you could just import this library and it would just work normally.
