Nuprl Lemma : eclass3-functional
∀[Info,B,C:Type]. ∀[X:EClass(B ─→ C)]. ∀[Y:EClass(B)]. ∀[es:EO+(Info)].
  (eclass3(X;Y) is functional) supposing (X is functional and Y is functional)
Proof
Definitions occuring in Statement : 
eclass3: eclass3(X;Y)
, 
es-functional-class: X is functional
, 
eclass: EClass(A[eo; e])
, 
event-ordering+: EO+(Info)
, 
uimplies: b supposing a
, 
uall: ∀[x:A]. B[x]
, 
function: x:A ─→ B[x]
, 
universe: Type
