I've always used Cython to make an extension. Speed improvements have always been awesome. I'm not sure when I'd want to use HPy over Cython. What are your opinions on this, please?

I think the idea is for cython to move away from generating CPython C API code to generating hpy code in the long run. From the point of view of cython users this won’t make much difference.

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 meetings where we started to talk about HPy and gave positive feedback on that.
