Apparently Rebindable doesn't support polymorphism. This is hopefully fixable.

A Rebindable variable can't be used as a switch argument. This would require a change to the language rules. However, the static immutable object Infos.one can be used as a case argument.
The conclusion is that Rebindable doesn't cover the needs of a mutable object reference.
In the flyweight pattern we only need to compare object addresses and we also want to use the lazy pattern to instantiate the immutable instances.
