I shouldn't have named it Wrapper, you could better think of it as a Widget with a position field, if that position is changed (and not just read from) then some kind of repaint mechanism would be invoked. However I shouldn't invoke such a mechanism if the value of the payload hasn't actually changed, so I should have a check inside of opAssign/opOpAssign. Additionally, "payload" might have its own functions which change its internal state. So to work around this, I would have to introduce opDispatch as well. Here's what I have so far: http://codepad.org/uSEMcD0g In the sample the Point structure is missing operator overloads, but if it had them they would be trapped by TrackChanges.
