Downto Operator

In C the so called "downto" operator is a 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.
