Proof step 2 from proof valid-eraseqp-in (previous step)

wlar[n] = wl-entry(m, stat), valid-eraseq(wlar, q), n ∈ q ⊦ wlar[n] = wl-entry(m, erasing)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
wlar[n] = wl-entry(m, stat), n ∈ q, ∀ n. n ∈ q ↔ n < # wlar ∧ wlar[n].status = erasing ⊦ wl-entry(m, stat) = wl-entry(m, erasing)

Rule argument

Additional information

Used simplifier rules: valid-eraseqw: ⊦ valid-eraseq(wlar, q) ↔ (∀ n. n ∈ q ↔ n < # wlar ∧ wlar[n].status = erasing);
