Nuprl Lemma : hdf-compose2_wf
∀[A,B,C:Type]. ∀[X:hdataflow(A;B ─→ bag(C))]. ∀[Y:hdataflow(A;B)]. X o Y ∈ hdataflow(A;C) supposing valueall-type(C)
Proof
Definitions occuring in Statement :
hdf-compose2: X o Y,

uimplies: b supposing a,
uall: ∀[x:A]. B[x],
member: t ∈ T,
function: x:A ─→ B[x],
universe: Type,
bag: bag(T)
