Proof step 24 from proof isarray-addarray-01 (previous step)

st[r1 -- _type] .type = mkarraytype(ty0), okarray(r1, ty0, addarray(r0, ty, vals, st)), is_arraytype(st[r1 -- _type] .type), is_typevalue(st[r1 -- _type]), r1 -- _type ∈ st, r1 ∈ st ⊦ r1 = jvmref, r1 = r0, is_array(r1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
st[r1 -- _type] .type = mkarraytype(ty0), r1 ∈ st, r1 -- _type ∈ st, is_typevalue(st[r1 -- _type]), okarray(r1, ty0, addarray(r0, ty, vals, st)) ⊦ r1 = r0, r1 = jvmref, is_array(r1, st)
