in my tests, if i do
package My;
use base qw(Foo Bar Baz);
sub new { ... }
package main;
my $my = My->new();
then of the following three expressions, only the first
evaluates to true:
$my->isa('Foo')
$my->isa('Bar')
$my->isa('Baz')
tangent: do you know of an easy way to print out a class'
inheritance tree?
