Proof step 51 from proof junkrefs-put-norefval-01 (previous step)

sk = fs ', okval(val, fs .type), is_fskey(sk), junkrefs(str, refs, ty, st[r1 -- sk, val]) ⊦ fs .type = void_type, sk = _length, is_referencevalue(val), junkrefs(str, refs, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 50:
okval(val, fs .type), junkrefs(str, refs, ty, st[r1 -- fs ', val]) ⊦ fs .type = void_type, fs ' = _length, is_referencevalue(val), junkrefs(str, refs, ty, st)
