How to explicitly declare an array of hashes?

[Richard Heintze]

Is there a way I can explictly declare that each array
cell contains a hash?

Here is the only way I know to do it:

my @PCEs=[];
while ($Data->FetchRow()) {
  my %dh = $Data->DataHash();
  $PCEs[$cn]{$dh{"id"}} = $dh{"ridPCE"};
}

This "my" declaration only says that it is an array,
not an array of hashes. Can I improve upon this?

     Thanks,
       Sieg
