Typo respectively wrong. I won't use 
$is_my_class = defined($object) && $object->isa('My::Class');

[download]
because if $object is defined but not blessed...

I'll use 
$is_my_class = eval { $fd->isa('My::Class') };

[download]
although normally (and I don't know why) I try to avoid 'eval'.
And although I'm not sure if I like this statement.
