The way I'd do this is <https://github.com/timotheecour/Nim/issues/598> which would allow user code to be registered as vmops, which run natively: proc fn(a: int): int {.vmhook.} = # this will be compiled as machine code # and run like a vmops ... Run
the 2nd ingredient is cling, which allows incremental C/C++ compilation based on clang (refs <https://github.com/timotheecour/Nim/issues/705>) which provides fast compile times (suitable for JIT) and high performance code generation (close to what you'd get from compiling via clang directly)
