I was just wondering if there's any way to extend an existing class in perl 6. I'd like to be able to do things like drop a custom debugging method in Any that would then be available on everything.
Note: I'm talking about adding something to an existing class
("monkeypatching") as opposed to subclassing. In perl 5 land you
can just say "package Whatever;" again and re-open an existing
package. With perl 6 saying "class Whatever" a second time would
be a "Redeclaration" error.
