Proof step 5 from proof addarrays-at-other-01 (previous step)

posints(ints), r ∈ st ⊦ ints ≠ [], (addarrays(newref_list(i→n(countrefs(ints)), st), ty, ints, i, st)[r -- sk]) = st[r -- sk]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ countrefs([]) = 1
Proof step 4:
r ∈ st ⊦ (addarrays(newref(st) ', ty, [], i, st)[r -- sk]) = st[r -- sk]

Rule argument
