I like this proposal as well, though there is currently a problem with 
the proposal that have to be worked out.

     <!-- lots of text -->

    /* overflow syntax needed */

Obviously, BAR overflows FOO, but the current proposal only addresses 
text (which is also the only real world usecase).

There are a number of options which could be chosen (dropping the 
'::overflow' pseudo element for now, since the less pseudo elements is 
the better for CSS3):

  * Something in the lines of 'overflow:move-to(blah) visible'. 'move-to'
    applies to the text, where 'visible' applies to the overflown boxes.
  * A property 'text-overflow'.
  * Some sort of syntax that extends the 'content' property. Something
    like 'content:normal overflow(blah)'.

Any suggestions?
