These new Assign methods are going to get really scary really fast when code get obsured behind an = sign. Imagine debuging a code fragment like "this.that = x" when it crashes the system. Or when this.that = y causes your entire interface to dance around and change colors.

I guess that its going to take sane programmers and great documentation to avoid a mess of problems!

Heck, I even avoid programaticly modifing/adding form elements to avoid confusion. :)
