Just to clarify the 5.005_63 behavior, for people who may want to vote #3,
perl 5.005_63 has these "features"/warts:

  * delete does not work on pseudo-hashes
  * exists still tests "uninitialized" state of underlying array element
  * there is no way to get exists() to return false on a pseudo-hash
    element if it is assigned to at least once
