This protocol has some behaviour callbacks, one of them is `empty/0`. So I cannot do MyProtocol.impl_for(term) because in that callback there is no term (I am returning a term though). https://github.com/eksperimental/buildable/blob/a2aa7658e58820472f56e7b1b7e3b3e2293c7950/lib/buildable/delegation.ex#L14
So what are my options for delegating to MyProtocol.MyImplementation ?
