thank you for the feedback! I wasn't aware of these features of Zulip, there are way too many competing technologies in this space and I miss the days in which everybody was IRC and that's it.

I haven't fully decided which route to take in that direction, but I think I'd like to support something similar do "go": you declare an interface (or, in python typing terms a Protocol) and then all the types which have

This looks exactly what I'm trying to do with SPy -- although SPy is still "not there" and it's WIP. I literally wrote an intro post about it yesterday: https://antocuni.eu/2025/10/29/insid

pypy IS compatible with C extensions, via what we call "cpyext": https://doc.pypy.org/en/latest/faq.html#do-c-extension-modul... The problem of cpyext is that it's super slow, for good reasons: htt

From many points of view, what CPython JIT can do is a subset of what PyPy can do. The biggest differences between the two JITs are: 1. PyPy is meta tracing, CPython is tracing 2. PyPy has "standard" code generation backends, CPyt

(author of the blog post here) "just compile when you know the types" is not a good strategy for Python. My EuroPython talk "Myths and fairy tales about Python performance" explains many reasons why Python is VERY hard t

(SPy author here) function calls in SPy are as cheap as in C. You can check by yourself seeing of the spy compiler translates the code to C in the (super-experimental) spy playground: https://antocuni.pyscriptapps.com/spy-pl

PyPy's difficulty with invoking native code is not because of its tracing JIT but because the CPython C API makes it very hard to deviate from _any_ CPython implementation details, including e.g. choice of memory management and precise

what is the python implementation you are involved with? I agree with your concerns, HPy tries to address them since the beginning. Basically, there are two distinct compilation modes: - CPython ABI: in this mode, things like HPy_Dup and HP

We plan to introduce something similar to CPython's argument clinic eventually. I.e., you will be able to declare what is the C signature of your impl function and HPy will generate the argument parsing code automatically. One nice eff

We plan to write a porting guide and examples at some point, but we didn't yet, also because we are still in the experimental phase and the API is still subject to change (although it changes less quickly nowadays). In theory, most of

hello, OP of the blog post here. Yes, the plan is to write a Cython backend at some point, so that all Cython extensions will benefit from HPy automatically. The main Cython developer (Stefan Behnel) was present during the very first few me
