Ah; in this case I want to keep the redefinition. When decoding an [`RpbSearchDoc`](https://github.com/basho/riak-ruby-client/blob/d12842124292153d35c6f7dd5d8812f271a16d29/lib/riak/client/beefcake/messages.rb#L471) I want to access the `RpbPair` objects that make up the search results from Riak, not the list of protocol buffers fields that an `RpbSearchDoc` message supports.
