Nuprl Lemma : lookup-list-map-find_wf
∀[Key,Value:Type]. ∀[deqKey:EqDecider(Key)]. ∀[key:Key]. ∀[m:lookup-list-map-type(Key;Value)].
  (lookup-list-map-find(deqKey;key;m) ∈ Value?)
Proof
Definitions occuring in Statement : 
lookup-list-map-find: lookup-list-map-find(deqKey;key;m)
, 
lookup-list-map-type: lookup-list-map-type(Key;Value)
, 
deq: EqDecider(T)
, 
uall: ∀[x:A]. B[x]
, 
unit: Unit
, 
member: t ∈ T
, 
union: left + right
, 
universe: Type
Definitions unfolded in proof : 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
lookup-list-map-find: lookup-list-map-find(deqKey;key;m)
, 
lookup-list-map-type: lookup-list-map-type(Key;Value)
Latex:
\mforall{}[Key,Value:Type].  \mforall{}[deqKey:EqDecider(Key)].  \mforall{}[key:Key].  \mforall{}[m:lookup-list-map-type(Key;Value)].
    (lookup-list-map-find(deqKey;key;m)  \mmember{}  Value?)
