halecommarachel has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
I have a hash reference that's about three levels deep, i.e. $info->{$os}->{$testcase}->{error}
I would like to create an array with all the 'error' values, for every $testcase and $os. How can I do this?
Thanks!
