--- Comment #2 from Adam D. Ruppe <destructionator at gmail.com> ---
Number of entries might be useful though, can't the compiler just issue a
void*[] when asked instead of a void**?

The object instance might only be void** since the length I don't think is
actually stored and that's a dynamic object, plus backward compatibility abi
etc. But for the static type the compiler knows so it can tell at no additional
cost.
