## Detailed Description

ValueImp is the base type for all primitives (Undefined, Null, Boolean, String, Number) and objects in ECMAScript.

Note: you should never inherit from ValueImp as it is for primitive types only (all of which are provided internally by KJS). Instead, inherit from ObjectImp.
