FloydATC has asked for the wisdom of the Perl Monks concerning the following question:
From here, I want to inherit the constructor and some other stuff in subclass like so:package Foo::Bar; use Carp; our @ISA = (); 1; sub new { my ($class, %opt) = @_; my $self = {}; bless ($self, $class); $self->init(%opt); return $self; }
Why then, does my test script not work??package Foo::Bar::Baz; use strict; use warnings; use Carp; our @ISA = qw( Foo::Bar ); 1; sub init { my $self = shift; my %opt = @_; # do the actual init for this specific class }
but instead yield an error: Can't locate object method "new" via package "Foo::Bar::Baz" at ./huh line 107. It's like the @ISA doesn't exist, what's going on?? I must have done this a million times but for some reason it doesn't on this machine... This is perl 5.8.8 on a Gentoo Linux and I'm ashamed to say this simple thing has had me stuck for over an hour now :-|#!/usr/bin/perl use strict; use warnings; use Foo::Bar::Baz; my $item = Foo::Bar::Baz->new();
