Python has a useful optional else clause on for loops. The else clause is executed unless the loop exits with a break.

See here: http://docs.python.org/ref/for.html

Example:

for(int i=0; i<10; i++) {
  if (a[i] == b) {
    printf("found at index %d\n", i);
    break;
  }
} else {
   printf("not found\n");
}

It should be pretty trivial to implement, and is a useful feature.

I'd prefer it be named "after" then "else" could be used if the loop never executes even once.
