* Principal. Moreover, objects obtained from the wrapper (including properties

* call to SpecialPowers.wrap(), the wrapper layer is transitively maintained.
|

*
|
|
* Known Issues:
|
|
*
|
|
* - The wrapping function does not preserve identity, so
|
|
* SpecialPowers.wrap(foo) !== SpecialPowers.wrap(foo). See bug 718543.
|
|
*
|
|
* - The wrapper cannot see expando properties on unprivileged DOM objects.
|
|
* That is to say, the wrapper uses Xray delegation.
|
|
*
|
|
* - The wrapper sometimes guesses certain ES5 attributes for returned
|
|
* properties. This is explained in a comment in the wrapper code above,
|
|
* and shouldn't be a problem.
