The only reason this is true is that in the second case you are resolving
the object twice. It is not true in general - the second time the long id
is used it will use the id cache which is constant time, whereas "button n"
is O(n). Try benchmarking repeated use of the stored long id vs the number
version, especially if the numbers are large.

So it's horses for courses. If it's a one-shot object access then the
number form is faster. For repeated use, get the long id.
