> Affects Versions: master
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Minor
>
> Provide a method for generic user-defined functions to clone a
> {{CopyableValue}}. A common use case is a {{GroupReduceFunction}} that needs
> to store multiple objects. With object reuse we need to make a deep copy and
> with type erasure we cannot call new.
