Proof step 41 from proof instore-afterputs (conclusion)

⊦ ¬ _type ∈ fv + fis ∧ instore(r, class, fv + fis, st) ∧ unique_al(fv + fis) ∧ st1 = st[r -- fv .1, refval(r1)] → instore(r, class, fis, st1) ∧ instore(r, class, (fv .1 × refval(r1)) ', st1)

Proof step 40:
instore(r, class, fv ' + fis, st), unique_al(fv ' + fis) ⊦ _type ∈ fv ', _type ∈ fis, instore(r, class, fis, st[r -- fv .1, refval(r1)]) ∧ instore(r, class, (fv .1 × refval(r1)) ', st[r -- fv .1, refval(r1)])
