I guess his suggestion would be something like this:

ElementType!(R) front ();

void foo (R) (R r) if(implements!(InputRange!(R)))
Personally I think it's nice to have a concrete type like this.
I perfectly understand his suggestion as I have implemented it
already few times ;) Again - it is nice, but does not give you
any real advantage unless can also be used with `wrap`.
