Proof step 29 from proof pathex-putstatfield (previous step)

validrefs(str, refs, mkclasstype(`java.lang.Object' .class), st) ⊦ refs = [], path∃(str, refs .first, refs .last, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 28:
refs = r + refs0, validrefs(str, refs, mkclasstype(`java.lang.Object' .class), st) ⊦ refs = [], path∃(str, r, refs .last, st)
