Nuprl Lemma : eager-map-append_wf
∀[T:Type]
∀[A:Type]. ∀[f:A ⟶ T]. ∀[as:A List]. ∀[bs:T List]. (eager-map-append(f;as;bs) ∈ T List) supposing value-type(T)
Proof
Definitions occuring in Statement :
eager-map-append: eager-map-append(f;as;bs),
list: T List,
value-type: value-type(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
eager-map-append: eager-map-append(f;as;bs),
so_lambda: λ2x y.t[x; y],
has-value: (a)↓,
so_apply: x[s1;s2]
