Proof step 16 from proof validstatfields-put-norefval-field-better (previous step)

okval(val, fs .type), validstatfields(str, st) ⊦ fs ' = _length, is_referencevalue(val), validstatfields(str, st[r -- fs ', val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 15:
fs = mkfs(class, ty, fieldvar), okval(val, ty), validstatfields(str, st) ⊦ fs ' = _length, is_referencevalue(val), validstatfields(str, st[r -- fs ', val])
