role Metamodel::PrivateMethodContainer { ... }

Warning: this role is part of the Rakudo implementation, and is not a part of the language specification.

In Raku, classes, roles and grammars can have private methods, that is, methods that are only callable from within the class, and are not inherited by types derived by inheritance.

class A {
    # the ! declares a private method 
    method !double($x) {
        say 2 * $x;
    }
    method call-double($y) {
        # call with ! instead of . 
        self!double($y);
    }
}

For the purposes of dispatching and scoping, private methods are closer to subroutines than to methods. However they share access to self and attributes with methods.
