On a side note, this might not do what you expect:
return @{$self->{'identities'}};
} else {
return undef;
Since you seem to be pulling the results of this in a list context, your resulting array will contain something like this:
@success = ($identity1, $identity2, $identity3);
@failure = (undef);
Either way, a test of
@array in a scalar context is going to get you a non-zero/true value either way. Get into the habit of calling
return witn no arguments when you want to return a 'false' value. This will return undef in a scalar context and an empty list in an array context, giving you the results you're looking for.
} else {
return;
