the size of the array will shrink to the highest element that tests
true for exists() (or 0 if no such element exists).

+Returns a list with the same number of elements as the number of elements
+for which deletion was attempted. Each element of that list consists of

a hash tied to a DBM file deletes the entry from the DBM file. Deleting
from a C<tie>d hash or array may not necessarily return anything.
