Yeah, that will be too costly because it would have to make a server call pretty quickly to confirm that the code is complete. (The Roslyn desktop C# Interactive can do this because it's right on the desktop)

You can press Ctrl-Enter to send complete code, if you wish to send submissions faster.

Yeah, I understand. My expectations were just set a bit higher since you called it a REPL. Realistically, something like this fills a different use case anyway. When I want a REPL, I want to run it locally.
