that's clever, but how does it work?

  It doesn't when the error is in something clever you did with the type system (e.g. wildly interdependent generics pretending to be scala). But for many simpler cases (e.g. the majority of idiomatic java), it can be as simple as substituting an offending imperative line with a throw RuntimeException statement that parrots the compiler error message. I'm sue that they are doing a lot more than that.
