I'd get rid of the pattern matching and put the valid keys in their own
hash:
my %valid = (
'acc1' => 1,
'acc2' => 1,
'acc3' => 1
);
while (my ($key, $value) = each (%hash)) {
if ($valid{$key})
### This seems cleaner to me. Also, if this has to be done many
### times you should see an improvement in performance too,
### but not if you only run through a short list once.
