JSONRPCError.error_respond maybe missing underscore?

AttributeError: 'JSONRPCError' object has no attribute 'jsonrpc_error_code'. Did you mean: '_jsonrpc_error_code'?

Is it that https://github.com/mbr/tinyrpc/blob/master/tinyrpc/protocols/jsonrpc.py#L174 (and line 180) need to lose the leading _ on assignment to self._jsonrpc_error_code so that JSONRPCError is aligned with the existing exception types above it (like JSONRPCServerError) which have a jsonrpc_error_code class attribute?
