This is such an end of an era that fresh Python programmers can’t even fathom.

PyPy used to be our hope! No major Python conference that didn’t suggest that they’re gonna fix the GIL and make time go backwards. And yeah, it’s really fast! I suspect the money-backed focus on performance in CPython combined with the compat paper cuts PyPy always came with has sealed its fate. I‘ve watched its decline over the years so I’m not surprised, but damn.

@hynek, for me it was always a fun project that tested whether packages aren't relying too deeply on CPython internals. It also helped to find a fair number of bugs in pure Python fallbacks of CPython stdlib that aren't normally used at all.

@mgorny @hynek yeah damn, and with CPython being renamed to RustPython and ensloppified…

MicroPython perhaps?

@kabel42 @mgorny @hynek PyPy implementing Python 3.11 only, which scientific-python extensions were actively recommended to drop last quarter (one early, their recommendation generator skips the last partial quarter of support).
