/**
* There was an incorrect sort behaviour 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
