Proof step 4 from proof getarray-length (conclusion)

⊦ 0 ≤ st[r -- _length] .intval → # getarray(r, st) = i→n(st[r -- _length] .intval)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
0 ≤ st[r -- _length] .intval ⊦ # getarray(r, st) = i→n(st[r -- _length] .intval)

Rule argument
