Proof step 39 from proof instore-afterputs (previous step)

fv = sk × val, instore(r, class, fv ' + fis, st), unique_al(fv ' + fis) ⊦ _type ∈ fv ', _type ∈ fis, instore(r, class, fis, st[r -- sk, refval(r1)]) ∧ instore(r, class, (sk × refval(r1)) ', st[r -- sk, refval(r1)])

Proof step 38:
instore(r, class, (sk × val) ' + fis, st), unique_al(fis) ⊦ _type = sk, _type ∈ fis, sk ∈ fis, instore(r, class, fis, st[r -- sk, refval(r1)]) ∧ instore(r, class, (sk × refval(r1)) ', st[r -- sk, refval(r1)])
