Re: Proposal for cleanup of RPC section (issue 195)

 Noah,
 the proposal in its fullness effectively says that return value 
is just another out parameter which means that the messages are 
self-describing. Some language bindings may choose to represent 
one of the out parameters as the return value, but that's their 
choice and it doesn't affect the messages.
 In the partial proposal (the hopefully uncontroversial part),
the situation in the return value is explicitly named therefore
the message is self-describing. In the array case, the return
value is again just another out parameter, so we're ok again.
 So I believe we're not adding any dependence and we might be
removing some, too.
 Best regards,
