Nuprl Lemma : State-loc-comb-functional

[Info,B,A:Type]. ∀[f:Id ─→ A ─→ B ─→ B]. ∀[init:Id ─→ bag(B)]. ∀[X:EClass(A)]. ∀[es:EO+(Info)].
  (State-loc-comb(init;f;X) is functional) supposing 
     (single-valued-classrel(es;X;A) and 
     (∀l:Id. single-valued-bag(init l;B)) and 
     (∀l:Id. (1 ≤ #(init l))))
