Such a user function would be todays best practice since
neither a userfunction setor($val, $else) nor an internal implementation
of such a function would work. Here Derick's argument comes into place that
we cannot simply change the way variables and array offsets are accessed.

The above setor_array() doesn't have that problem though.
