Two ways, actually. You can 'reopen" the String class and add the method:
class String is extended {
method scramble () returns String {...}
}
or if you consider that underhanded, you can define a multi-sub:
multi sub *scramble (String $s) returns String {...}
If you call that as a method, and there is no ordinary scramble method,
it will "fail soft" to looking for a scramble multimethod, and end up
calling your definition. Or you can just call it directly as a function:
scramble("hello")
