Wow.  That's sure the long way around for what I would use this for:

sub blessed {
        my $item = shift;
        local $@; # don't kill an outer $@
        ref $item and eval { $item->can('can') };
}

We call it "doing the can-can". :)

And this solution has the advantage that it doesn't pollute UNIVERSAL.
