rpc FUNC(stream TYPE1) returns (TYPE2) {};	stream.Recv() &&	stream.Send(TYPE1) &&
	stream.SendAndClose(TYPE2)	stream.CloseAndRecv()
rpc FUNC(TYPE1) returns (stream TYPE2) {};	stream.Send(TYPE2)	stream.Recv() && EOF
rpc FUNC(stream TYPE1) returns (stream TYPE2) {};	stream.Recv() && EOF	stream.Recv() && EOF &&
	stream.Send(TYPE2)	stream.Send(TYPE1) && stream.CloseSend()
