Now that user classes are real classes, the old swf bug that lhs
references will not be found in a with(this) if they are only
inherited via the prototype is biting me. We've documented for years
that you need to use `this.` on lhs of =, but there seems to be a
regression test that expects this to work.
(Of course, things just work in DHTML)
My choices appear to be:
a) For as2, each time you make an instance, copy all it's prototype
properties into the instance (Effectively making hasOwnProperty
useless).
b) Fix the regression test, and wait for fallout from user programs
Thoughts?
