Proof step 7 from proof validstatfields-put-norefval-field-better (previous step)

okval(val, ty), sk ∈ statfields(class0), initdone(class0, st), tdname∃(str, class0), validstatfield(str, sk, st), r ≠ jvmref ∨ class ≠ class0 ∨ ty ≠ void_type ∨ fieldvar ≠ `initstate' .field ⊦ mkfs(class, ty, fieldvar) ' = _length, r -- mkfs(class, ty, fieldvar) ' = _uninit, validstatfield(str, sk, st[r -- mkfs(class, ty, fieldvar) ', val]), is_referencevalue(val)

User applied rule insert rewrite lemma
