REPL (like in Python)

[Akuli]

I think it would be possible to make a REPL with LLVM. However, I don't think I want to implement it into the compiler I currently have, because currently a compiler error exits the entire process. Maybe if I write a self-hosted compiler some day.

A toy repl made in python, based on your crepl(That repo is really great)!

I don't know why, but a REPL for a compiled language seems kinda cursed.
