Proof step 5 from proof Comp-get-02 (previous step)

getarray(r1, i1, j, st) = getarray(r2, i2, j, st), 0 ≤ i, i < j, 0 < j, ∀ i0. ¬ i0 < 0 ∧ ¬ j ≤ i0 → st[r1 -- (i1 + i0) '] = st[r2 -- (i2 + i0) '] ⊦ st[r1 -- (i1 + i) '] = st[r2 -- (i2 + i) ']

Heuristic quantifier closing applied rule all left

And closed the goal!
