Downto Operator

   In [1]C the so called "downto" operator is a [2]joke played on nubs. It
   goes like this: Did you know C has a hidden downto operator -->? Try it:

 #include <stdio.h>

 int main(void)
 {
   int n = 20;

   while (n --> 10) // n goes down to 10
     printf("%d\n",n);

   return 0;
 }

   Indeed this compiles and works. In fact --> is just -- and > operators.
