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?)
