Has anyone thought of the possibility of 'named' loops?

for outer (x = 0; x < MAXX; x++)
{
   for inner (y = 0; y < MAXY; y++)
   {
      if (map[y][x] == '*')
         break (outer);
   }
}

As far as I can see this would not cause any ambiguities, is logical, extensible,
and fun for all ages :)

I thought of this about a week or two ago while pondering this problem and as I am 
currently playing with C parsing, I might try to implement it in a grammar.

Does anyone have any thoughts on this idea?
