  Log:
    Call initialize_clone with freeze: false if clone called with freeze:=
 false
    =

    This makes it possible to 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.
