Proof step 42 from proof junkrefs-delete-02 (previous step)

∀ str, ty, st, r. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st -- r), junkrefs(str, r0 + acc, ty, st) ⊦ junkrefs(str, r0 + acc, ty, st -- r)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 41:
junkrefs(str, r0 ' + acc, ty, st), ∀ str, ty, st, r. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st -- r) ⊦ junkrefs(str, r0 ' + acc, ty, st -- r)

Rule argument
