You don't need to prefix subroutine calls with &. Thats a throwback from perl 4 like 10 years ago? I dunno for sure, sometimes I see it. Its ugly and extra work anyways!.

Nested dereferencing "arrows" (->) can be ommitted. I'm not sure how best to describe it, but here is the before:

my $category = lc($musing_cats->{$ref_id}->{'ref_name'});

After:

my $category = lc $musing_cats->{$ref_id}{'ref_name'};
