Yes, but then  you get back into calling through the ObjC runtime, which is
where things bogged down.  Since you'd go through BCSequence, then into
NSArray, it would be even worse than just calling it on the array.

Not that the method wouldn't be a bad one, just that it would have a
negative speed impact.
