Unset(), when applied to array elements, leaves holes in the array.

Take this code:
$array = array("a");
$array[] = "d";

This will produce the following output with PHP 3.0.12 and 3.0.13:
array(2) {
  string(1) "d"

a) It would make more sense if the index would be 0.
b) var_dump() sees the array as containing two elements. Count() works fine, though. PHP 4.x's var_dump() shows correctly array(1).

We are sorry, but can not support PHP 3 related problems
anymore.  Momentum is gathering for PHP 5, and we think
supporting PHP 3 will lead to a waste of resources which
we want to put into getting PHP 5 ready. Ofcourse PHP 4
will continue to be supported for the forseeable future.

for a) unset doesn't renumber, remember that all php
       arrays are actually hashes
    b) well, see message above
