Proof step 13 from proof validstatfields-put-norefval-field-better (previous step)

okval(val, ty), validstatfields(str, st) ⊦ mkfs(class, ty, fieldvar) ' = _length, is_referencevalue(val), ∀ class0, sk. tdname∃(str, class0) ∧ initdone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]) ∧ sk ∈ statfields(class0) → validstatfield(str, sk, st[r -- mkfs(class, ty, fieldvar) ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
validstatfields(str, st), okval(val, ty), sk ∈ statfields(class0), initdone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]), tdname∃(str, class0) ⊦ mkfs(class, ty, fieldvar) ' = _length, validstatfield(str, sk, st[r -- mkfs(class, ty, fieldvar) ', val]), is_referencevalue(val)
