Proof step 7 from proof switch-obj (previous step)

⊦ r = r0, addarray(r, ty, vals, addobj(r0, class, fis, st)) = addobj(r0, class, fis, addarray(r, ty, vals, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ addarray(r, ty, vals, st) = addarray(r, vals, 0, st[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))])
Proof step 6:
⊦ r = r0, addarray(r, vals, 0, addobj(r0, class, fis, st)[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))]) = addobj(r0, class, fis, addarray(r, ty, vals, st))

Rule argument

[crewrite-arg: addarrayinit-def , F , [st, vals, ty, r] → [addobj(r0, class, fis, st), vals, ty, r] ]
