/**
 * There was an incorrect sort behavior documented in issue #143:
 * (x = f(…)) <= x → x >= (x = f(…))
 *
 * For example, let the equation be:
 * (a = parseInt('100')) <= a
 *
 * If a was an integer and has the value of 99,
 * (a = parseInt('100')) <= a → 100 <= 100 → true
 *
 * When transformed incorrectly:
 * a >= (a = parseInt('100')) → 99 >= 100 → false
