The problem is that interfaces are a runtime thing (e.g. you can cast a

structs implement compile time interfaces via template duck typing

you could probably write a wrapper that introspected an interface and
enforced that all members were implemented.
I've actually thought about doing this to get rid of a bunch of if
qualifiers in my function declarations. `static interface {}` compiles but
doesn't [currently] seem to mean anything to the compiler, but could be a
hint to the programmer that nothing will directly implement it; it's a
compile-time interface. This would provide a more generic way of doing
stuff like `isInputRange`, etc.
Or we could get signatures, which are even better still!
