We override equals so that for method identity checks we treat delegating wrappers the same as the original methods. See e.g. RubyClass.finvokeChecked and its method_missing comparison.
    public boolean equals(Object other) {
        if (other instanceof DelegatingDynamicMethod) {
            return .equals(((DelegatingDynamicMethod)other).getDelegate());
        }
        return .equals(other);
    }
