Thank you! That's exactly what I was aiming for. That sounds like a good idea. The problem is that I just don't know enough about compilers, Julia's internals, and how the core dev team works to really forecast the future and know what's possible. How hard would it be to implement caching of native code? A fast interpreter that runs side by side with the compiler? No idea. Maybe it would still be useful to make a post explaining how I cope with the limitations of Julia. I'll think about it.
