Feature #16129: Call initialize_clone with freeze: false if clone called with freeze: false

• Status: Closed

This makes it possible for initialize_clone to correctly not freeze internal state if the freeze: false keyword is passed to clone.

If clone is called with freeze: true or no keyword, do not pass a second argument to initialize_clone to keep backwards compatibility.

This makes it so that external libraries that override initialize_clone but do not support the freeze keyword will fail with ArgumentError if passing freeze: false to clone. I think that is better than the current behavior, which succeeds but results in an unfrozen object with frozen internals.

The attached patch implements this support and fixes related issues in set and delegate in stdlib.
