I mean when we do equality test, Index outside range not producing error

Cas> m := [1,2,3]
Cas> m[3] == m[4]      → 0
Cas> m[4] == m[5]      → 0
Cas> m[5] == m[6]      → 0

m2[hi][1]==m2[hi+1][1] guard should also generate 0, i.e. always update last ranking.

If we use this undefined behavior (not recommended), we can drop ii≠hi guard.

Interestingly, I discovered this due to a typo , i≠hi instead of ii≠hi
Since i = √(-1) is imaginary, i≠hi is always true, same as no guard.
