Nope, it's brand new and possibly temporary. Erick doesn't
really like this as a way of specifying interfaces,
and I think I agree .. however I needed something that
didn't break lots of library code fast, to get typeclasses
working.
fun f:int->int;
isn't an interface .. it means
fun f: int -> int = "f($1)";
so I used
virtual fun f:int->int;
to specify an interface. But really the first form seems
right for an interface.. which means we'd need something
like
fun f: int -> int = auto;
for Felix to auto generate the C binding.
