A modern programming language that makes developers happier.

Calling `engine.eval()` on a small script is taking over six seconds, consistently. This looks crazy to me, is there any way to at least turn on some incremental compilation from the engine?

I’m pretty sure this has nothing to do with the incremental compilation. The all delays are quite likely due to the compiler warm-up times. There are ways to share the compiler in some sense, e.g. using the daemon (there is a sample implementation of JSR223 that uses this approach), but I’m not sure it fits the scenario you’re aiming at.

Yes, I was mentioning incremental compilation because evaluating the same script twice in a row should be instant the second time

The compiled scripts caching is a part of the new scripting infrastructure, I’m working on now. Hopefully it could help in such scenarios.
