Proof step 6 from proof switch-class-01 (previous step)

∀ r, i, class, fis, st. addarray(r, vals0, i, addclass(class, fis, st)) = addclass(class, fis, addarray(r, vals0, i, st)) ⊦ addarray(r, val + vals0, i, addclass(class, fis, st)) = addclass(class, fis, addarray(r, val + vals0, i, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ addarray(r, val ' + vals, i, st) = (addarray(r, vals, i + 1, st)[r -- i ', val])
Proof step 5:
∀ r, i, class, fis, st. addarray(r, vals0, i, addclass(class, fis, st)) = addclass(class, fis, addarray(r, vals0, i, st)) ⊦ (addarray(r, vals0, i + 1, addclass(class, fis, st))[r -- i ', val]) = addclass(class, fis, addarray(r, vals0, i + 1, st)[r -- i ', val])
