Yes there is. If a implementation of a protocol is incomplete, then the
compiler will complain. Also, knowing about a protocol before implementing it
seems like a good idea.

Also, I think that "looking up definitions is hard" is not a strong enough
reason to warrant this change.

A type can automatically fulfill requirements of some protocol right now. This
change would break that too.

So, -1.
