| File Name: 15.2.4.3.js |
| ECMA Section: 15.2.4.3 Object.prototype.valueOf() |
| |
| Description: As a rule, the valueOf method for an object simply |
| returns the object; but if the object is a "wrapper" |
| for a host object, as may perhaps be created by the |
| Object constructor, then the contained host object |
| should be returned. |
| |
| This only covers native objects. |
