Minimum

Problem: Find the minimum of three (or more) values
Programming Style: Examples and Counterexamples contains this example:

        if ($x < $y) {
          if ($x < $z) {
            $small = $x;
          } else {
            $small = $z;
          }
        } else {
          if ($y < $z) {
            $small = $y;
          } else {
            $small = $z;
          }
        }

(Translated from the original FORTRAN.)
- (In 1974, FORTRAN had no ELSE, so imagine this with six GO TOs instead)
Improved version:

        $small = $x;
        if ($y < $small) { $small = $y }
        if ($z < $small) { $small = $z }

I don't know what to conclude from this, but it seemed to be worth pointing out
