The EcmaScript standard defines that all function and many
non-function properties of standard objects like Math. String etc.
should be DONTENUM. If you want to change the DONTENUM status of a
particular property, you can use ScriptableObject.get/setAttributes
methods to clear the Scriptable.DONTENUM  flag. If you want to make
all properties of your object to be visible in for (..in..) loop
ignoring DONTENUM,  you can override in your ScriptableObject subclass
getIds method like in:

public Object[] getIds() {
    return getAllIds();
}
