Re: Do not use UNIVERSAL::isa this way; but why?

Thank you all for your answers!

Well then... I think I'll 'switch' to

$is_my_class = defined($object) && $object->isa('My::Class');
[download]

since I used to write

$is_my_class = defined($object) && $UNNIVERSAL::isa($object, 'My::Clas
+s');
[download]

$is_my_class = eval { $fd->isa('My::Class') };
[download]

to preserve my keyboard! ;)

@ Tanktalus: uh... I've never thought about this. But I think I... yeah... the time will come when I'll have to write a Decorator! At least this came to my mind when I read your post.

narg 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. k	[reply] [d/l] [select]
