package A;

package B;
use strict;
use base 'A';
print Dumper([1]);

The above example does not work as namespaces are not inherited, and @ISA is not checked unless arrow notation is used (e.g. $foo->Dumper(1), which would result in $foo being passed as well).

Is there a clean way to automagically inherit the subs from 'A' when you use it as a base? i.e. Not using Exporter and EXPORT|EXPORT_OK.

The only thing that I came up with that would allow a lazy inheritance of subs from the namespace of @ISA is: 

sub AUTOLOAD {
    our (@ISA, $AUTOLOAD);
    use Symbol;
    my ($my_package,$method) = $AUTOLOAD =~ /^(.*)::(.*?)$/;
    for my $base (@ISA) {
        my $ref = qualify_to_ref($method,$base);
        next unless $ref && *{$ref}{CODE};
        # $method exists as a sub in $base.
        my $new_glob = qualify_to_ref($method,$my_package);
        # Copy the code reference from the base class to this one
        *$new_glob   = *{$ref}{CODE};
        # Magic goto so AUTOLOAD doesn't appear in the caller list
        goto &$new_glob;
    }
    use Carp 'croak';
    croak("Invalid method $method");
}
