>Description:
Wouldn't it be nice if loop commands (while, for etc) returned a value. The value is often needed if the loop is aborted. I mean:

--------------------------------------

if(
   for(i=0;;i++){
      if(i == 5)break;
   }
){
  printf("Loop didn't finish!");
}

--------------------------------------

This is needed very often when you'd like to exit the loop, so I consider this might not be a bug improvement  - but a nice feature.

State-Changed-Why:
    I think the present mood is very much against random extension
    to the language. If you think that your proposal is a good
    idea, try to take it to the respective standard committees
    and ask them to consider things. If approved, gcc will
    then certainly integrate this.
