It's an interesting trick, but for a setter method you really need to use `def cloaking=(value)` instead of overloading the same method. It would help to give a more realistic example for where this technique can be useful.

Please fix the indentation of the code -_-

What happens if you pass in (nothing_provided = true) as the value?

Does it return back the empty current value?

I’m no ruby expert, but seems like the freeze approach avoids that with a unique inaccessible object.

This expression returns true. It should be in a different scope from the default parameter value, so I assume it is equivalent to passing true directly.

Wow, I wrote Ruby for 15+ years and never saw this trick!

Same and it’s really unclear to me why you would want this access pattern over. It seems like it might lead to unintended consequences.
