My question is:

What's the commonly accepted syntax to do this? I've never used:
foreach my $record (@{$array_ref}) {

The notation I'm comfortable w/ is:
foreach my $record ( @$array_ref ) {

Is there an accepted standard?


astaines:
since you said you're still learning about refferences - you might want to try deref'ing them like so:
  my $arrayElement = $$arrayRef[0];
  my $hashValue = $$hashRef{someKey};

Also, you may want to checkout wantarray for returning array's or their references to the caller.

Hope this helps
