Detailed Description
Value objects are act as wrappers ("smart pointers") around ValueImp objects and their descendents.
Instead of using ValueImps (and derivatives) during normal program execution, you should use a Value-derived class.
Value maintains a pointer to a ValueImp object and uses a reference counting scheme to ensure that the ValueImp object is not deleted or garbage collected.
Note: The conversion operations all return values of various types - if an error occurs during conversion, an error object will instead be returned (where possible), and the execution state's exception will be set appropriately.
