Proof step 23 from proof compatval-put (previous step)

compat(str, val, ty, st) ⊦ fs .type = void_type, compat(str, val, ty, st[r -- fs ', val0])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 22:
fs = mkfs(class, ty0, fieldvar), compat(str, val, ty, st) ⊦ ty0 = void_type, compat(str, val, ty, st[r -- fs ', val0])

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty0, fieldvar] ,T ,fieldspec , ,elim ]
