// This little program takes ~ 6 seconds to compile on my MacBook Pro Late 2013.
// It compiles and works as expected. But the type checker spends a lot of time
// on the function at the end.
// In my actual project, I have much more code like this, and it results in very
// long compile times. So I'd like to know if there is something I can do to
// speed that up.
