Proof step 18 from proof newrefs-butlast-01 (previous step)

∀ st. newref_list(m + 1, st) .butlast = newref_list(m, st) ⊦ newref_list(m +1 + 1, st) .butlast = newref_list(m +1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
∀ st. newref_list(m + 1, st) .butlast = newref_list(m, st) ⊦ newref_list(2 + m, st) .butlast = newref_list(m + 1, st)

Rule argument
