I'm not sure I like this polymorhic method-naming stuff that'll be happening in the background. Perl is weakly-typed, so why do a work-around that strongly-typed languages have to do? Instead, why not do the following?
sub new {
my ($class, $name, $rank, $c_num) = @_;
$name ||= '';
$rank ||= '';
$c_num ||= '';
bless { name => '',
rank => '',
cereal_number => '',
}, $class;
}
That, to me, just feels cleaner and is more maintainable. If you make a change in
new(), you only have to change it in one place. Especially if it's in a base class. If it's in a base class and you only change one, you suddenly have weird behavior in the grandchild classes and debugging it would take an age-and-a-half. *shudders*
