Proof step 16 from proof isarray-put-samefield-01 (previous step)

r -- fs ' ∈ st, oktype(st[r -- fs '], fs .type, st), oktype(val, fs .type, st), is_array(r, st[r -- fs ', val]), r ∈ st ⊦ fs ' = _length, fs ' = _type, is_array(r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 15:
fs = mkfs(class, ty, fieldvar), r -- fs ' ∈ st, oktype(st[r -- fs '], ty, st), oktype(val, ty, st), is_array(r, st[r -- fs ', val]), r ∈ st ⊦ fs ' = _length, fs ' = _type, is_array(r, st)

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty, fieldvar] ,T ,fieldspec , ,elim ]
