Proof step 2 from proof good-field-field-03 (previous step)

⊦ goodfieldandtype(r, fs ', st) ↔ r -- fs ' ∈ st ∧ okval(st[r -- fs '], fs .type)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 1:
⊦ goodfieldandtype(r, mkfs(class1, ty, fieldvar) ', st) ↔ r -- mkfs(class1, ty, fieldvar) ' ∈ st ∧ okval(st[r -- mkfs(class1, ty, fieldvar) '], ty)

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 ]
