Nuprl Lemma : Accum-class-single-val0
∀[Info,A,B:Type]. ∀[es:EO+(Info)]. ∀[f:A ─→ B ─→ B]. ∀[X:EClass(A)]. ∀[init:Id ─→ bag(B)]. ∀[e:E]. ∀[v1,v2:B].
(v1 = v2 ∈ B) supposing
(v1 ∈ Accum-class(f;init;X)(e) and
v2 ∈ Accum-class(f;init;X)(e) and
single-valued-bag(init loc(e);B) and
single-valued-classrel(es;X;A))
