Let's extend the example a little. What if _method1 isn't defined, but is AUTOLOAD'ed instead? This isn't an unreasonable thing. So far, so good.

Now, let's say that the Foo class inherits from some CPAN module. This is a very common thing. Let's say we're inheriting from CGI::Application.

Now, let's say that CGI::Application adds a _method1() in the next version. Uh-oh. Your code breaks in very mysterious ways.

What if CGI::Application adds dependence on AUTOLOAD in the next version. Uh-oh. Your code breaks again, but in even _MORE_ mysterious ways. (Cause it's not your code that broke, but it sure looks like it!)

Perl6 fixes most (but not all) of these issues, which is a "Good Thing"™

I shouldn't have to say this, but any code, unless otherwise stated, is untested
