Tracing JITs in the Real World CPython Core Dev Sprint

IIRC Julia's is a particularly simple method-based JIT for a dynamically-typed language.

I'm not sure exactly how it differs from most JavaScript JITs, but I believe it just compiles each method once for each set of function argument types - for example, it doesn't try to dynamically determine the types of local variables.

I think the compiler figures that if a new method comes up, it’ll just compile that when it needs to.
