Smerity.com: Python isn't just glue, it's an implicit JIT ecosystem

Writing more Rust recently led me to a revelation about Python. Rust was vital to my original task, but only a few simplifications away, the shorter Python version leapt to almost as fast. I'd stumbled from a cold path to a hot path...

Looking closer, I began to see these hot paths everywhere in Python's ecosystem - well-worn trails connecting optimized nodes, paved over time by countless developers before me.

What struck me wasn't just finding a single optimized path, it was how everything worked so well together, across components not originally intended to be so tightly coupled. This pattern felt familiar. Pervasive even. This felt far more than just Python as a glue language.

The combination is what is most profoundly special, captured in the broader picture of how the Python ecosystem evolves and what directs that evolution.

When you write Python code you're not just writing glue, you are an explorer in Python's implicit just-in-time compilation ecosystem.
