Dear Monks.

In http://search.cpan.org/~rgarcia/perl-5.10.0/lib/UNIVERSAL.pm it is written:
# but never do this!
$is_io    = UNIVERSAL::isa($fd, "IO::Handle");
$sub      = UNIVERSAL::can($obj, "print");

[download]

But I don't get it. Why should I never do this and prefer 
$is_io = $fd->isa('IO::Handle');

[download]
?
Thank you for your answers!
