I noticed that `cargo check` alone is plenty fast, and when you give it a program with a type issue to check, it reports errors nearly instantaneously (< 0.5s).

So this is probably not all the type checking (including borrowchecking) that slows things down, but the phases that happen later, likely code generation. Which leads me to a question - why is code generation so slow even in debug mode compared to other compiled languages? (this is one thing that Golang does right).
