Proof step 12 from proof isobj-put-samefield-03 (previous step)

st[r -- _type] .type = mkclasstype(class0), r ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), okval(val, ty), is_obj(r, st) ⊦ r = jvmref, mkfs(class, ty, fieldvar) ' = _type, is_obj(r, class0, st[r -- mkfs(class, ty, fieldvar) ', val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 11:
st[r -- _type] = typeval(ty0), ty0 = mkclasstype(class0), r ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), okval(val, ty), is_obj(r, st) ⊦ r = jvmref, mkfs(class, ty, fieldvar) ' = _type, is_obj(r, class0, st[r -- mkfs(class, ty, fieldvar) ', val])
