ECMA V2 Section:

Description: Regression Test.
|
|
|
|
If instance Native Object have properties that are enumerable,
|
|
JavaScript enumerated through the properties twice. This only
|
|
happened if objects had been instantiated, but their properties
|
|
had not been enumerated. ie, the object inherited properties
|
|
from its prototype that are enumerated.
|
|
|
|
In the core JavaScript, this is only a problem with RegExp
|
|
objects, since the inherited properties of most core JavaScript
|
|
objects are not enumerated.
