Proof step 12 from proof valid-eraseq-next-erasing (previous step)

wlar[n] = wl-entry(m1, stat), n < # wlar, n < m, m < # wlar, n + 1 < # wlar, n ∈ q, ∀ n. n ∈ q ↔ n < m ∧ wlar[n].status = erasing ⊦ n = m, stat = erasing

Heuristic quantifier applied rule all left

And closed the goal!

Rule argument
