“Nice” doesn’t mean “well suitable for writing a compiler in”. It’s strange to think that all languages should be equally good for writing all kinds of things, and choosing a web language for a non-web task is doubly strange.

That was the Roslyn project! Yes they were also excited that it would allow more devs to hook into the computer and also enhance it.
