ActionScript is tricky for a compiler, because there
are circumstances where it *cannot* know which object
you're working on.
Consider this code:

    var o:Object;
        o.member = new String()
        o.member = new Matrix3D()

There's no way of telllng whether "o.member" is
a String or a Matrix3D, and hence, whether it'll
have the transpose() method or not.
