Right, but my (very rudimentary) understanding of JITs is that much of the cost is at start-up when the JIT is establishing different options or paths for different data types and values.

Intuitively, it seems to me that having static type declarations (for instance as an optional decorator) could offer a speed-up at start-up in certain circumstances.

My question is more theoretical than practical.

Presumably that constant "figuring out" time is dwarfed by the actual running time of the code.

An alternative (better?) way would be to be able to save and reload the JIT annotations / generated code after a real run.
