I found that in some cases checking to see if a hash element is defined will
add to the hash.
The following line:
103 if (defined $self->{keys}{cfg}{$varname}{ref_sub}) {
will add the hash element, $self->{keys}{cfg}{$varname}. I had to change my
code to the following in order to get it to work correctly.
102 if (defined $self->{keys}{cfg}{$varname}) {
103 if (defined $self->{keys}{cfg}{$varname}{ref_sub}) {
104 return $self->{keys}{cfg}{$varname}{ref_sub};
105 }
106 } else {
107 return undef;
108 }
I hope this helps anyone else who cares.
