In that sense almost every compiled Lisp/Scheme implementation, GHC, etc. or any other interactive programming system, count as JIT. But virtually nobody in those circles refer to such implementations as JIT. Instead, people says "I wish our implementation was JIT to benefit from all those optimizations it enables"!

Do they generate machine code in ram and jump to it? Or do they interpret byte code?

EDIT: at least GHC seems to be a traditional AOT compiler.

[kscarlet]

They generate native machine code.
