Proof step 58:
st[r -- _type] .type = mkarraytype(ty), st[r -- i '] = refval(r0), # refs = # sks0, is_array(str, r, st), fits(r0, sks0, st), validrefs(str, r0 ' + refs, st[r0 -- _type] .type, st), i < st[r -- _length] .intval, 0 < st[r -- _length] .intval, 0 ≤ i, ∀ sks1. sks1 ⊑ sks0 ∧ sks1 ≠ [] → st[r0 -- sks1] .refval = (r0 ' + refs)[# sks1] ⊦ r = jvmref, junkref(str, r0, st), junkref(str, r, st), validrefs(str, r0 ' + refs, ty, st), st[r0 -- _type] .type ≤ ty
