It's quite a bit more than a just new function since it brings some new
behaviours that we don't have for functions in Go at the moment:
1. like panic it interrupts its caller's control flow
2. It may only be used within functions/methods that have a particular
signature. Presumably it's a compile error to attempt to use it elsewhere.
3. It accepts any number of mixed type arguments without boxing into an
interface{}
