Some people have worked on a Rust REPL, but it wasn't really useable last time I checked. Part of the motivation to develop this was the possibility to use LLVM as a JIT, which is pretty nice.

Personally, I would love to see this as part of an IDE that can execute _parts_ of a Rust file with various inputs to quickly see if a function behaves as expected (this could also be easily converted into test cases.)

That's the idea. They're great for exploratory programming. In LISP, safety was optional. This was actually OK... would be in Rust... if your goal in that mode was to understand requirements, algorithm, solution space, etc. Get an idea of how you might handle it. Then, turn safety back on, try to get a solution going. When it works, compile that module. Future tweaks do incremental compilation.

Rapid development cycle doing features this way.
