 You can have *args, after an assoc. From parse.y :


                | assocs ','
                    {
                        $$ = NEW_LIST(NEW_HASH($1));
                    }
                | assocs opt_block_arg
                    {
                        $$ = NEW_LIST(NEW_HASH($1));
                        $$ = arg_blk_pass($$, $2);
                    }
                | assocs ',' tSTAR arg opt_block_arg
                    {
                        $$ = arg_concat(NEW_LIST(NEW_HASH($1)), $4);
                        $$ = arg_blk_pass($$, $5);
                    }
                | args ',' assocs opt_block_arg
                    {
                        $$ = list_append($1, NEW_HASH($3));
                        $$ = arg_blk_pass($$, $4);
                    }
                | args ',' assocs ','
                    {
                        $$ = list_append($1, NEW_HASH($3));
                    }
                | args ',' assocs ',' tSTAR arg opt_block_arg
                    {
                        $$ = arg_concat(list_append($1, NEW_HASH($3)), $6);
                        $$ = arg_blk_pass($$, $7);
                    }
