Nuprl Lemma : classrel-implies-member
∀[Info,T:Type]. ∀[X:EClass(T)]. ∀[es:EO+(Info)]. ∀[e:E]. ∀[v:T].  ↑e ∈b X supposing v ∈ X(e)
Proof
Definitions occuring in Statement : 
classrel: v ∈ X(e)
, 
member-eclass: e ∈b X
,

, 
event-ordering+: EO+(Info)
, 
es-E: E
, 
assert: ↑b
, 
uimplies: b supposing a
, 
uall: ∀[x:A]. B[x]
