Restarting Pyjion, a general purpose JIT for Python- is it worth it?
summary
Project restarts Pyjion as pidgin that compiles CPython 3.9 bytecode to machine code via uses .NET 5 RyuJIT, installs with pip installable and runs on Linux Mac and Windows x64. It claims 100% compatibility, attaches compiled binaries to code objects, implements ~15 pattern optimizations plus profile guided compilation, caches JITed symbols in RAM, and reports real results: n‑body runs at about one third the execution time of CPython and other benchmarks show ≈20% gains.
