    Although with just plane "as", you still have to check for null.  I'd like so see something like

    with (CheckBox chk = o as CheckBox)
    {
       // body
    }

    where body is only executed if o is a CheckBox.  This could be expanded out to...

    with (CheckBox chk = o as CheckBox)
    {
       // body
    }
    else with (ToolBarButton tbb = o as ToolBarButton)
    {
       // other body
    }
    else
    {
       // another body
    }

    That would be useful to me, and quite compact.  But I think "with" is a VB keyword, isn't it?
