Very well.  I just thought it would be a nice OOP feature to save time on
some people's behalf.

Hello scott,

  reason we are agsinst is that you can easily do i already in PHP.
Actually you can even do it in a manner everybody understands without
having to make the language more complex. Or in other words sometimes
it does not hurt doing a few keystrokes more. Instead it helps read-
and maintain-ability.

best regards
marcus
