I need to be able to call a function in a parent class, but I can't guarantee that the parent class will have that function. So, I've got something like: 

my $class = ref($self);
foreach my $parent (@{"${class}::ISA"}) {
    my $value = $parent->do_something
        if $parent->can('do_something');
}

This is a class method, not an object method, so it takes a class-name as the first arg. From what I've read about can(), it only handles blessed references.
