This would also improve the latency in the crystalline LSP. I tried to get into crystal lang, but the LSP needs to compile your code to give you completion etc.

This would also improve the latency in the crystalline LSP. I tried to get into crystal lang, but the LSP needs to compile your code to give you completion etc.. you can imagine how slow this is once you've compiled something in crystal. And I didn't even go further than writing ~10 lines of code. I can't imagine using this with a normal sized code base.
