In practice, the time consumed by the call-other itself is probably
not such a big deal. But it's typically a good idea to store return
values in a variable, yes, especially if you do not have absolute
control over what may happen inside query_reference_names() in the
future. Maybe somebody will change its internal implementation in
such a way that it becomes a backwards compatiblity function going
at some sluggish pace? I've seen it happen.

You can obfuscate your code quite a bit if you like it small:

	if (sizeof(current_object->query_reference_names() &
                   ({ name_test })) != 0) {
		return current_object;
	}
