Nuprl Lemma : M-return_wf
∀[Mnd:Monad]. (M-return(Mnd) ∈ ⋂T:Type. (T ⟶ (M-map(Mnd) T)))
Proof
Definitions occuring in Statement :
M-return: M-return(Mnd),
M-map: M-map(mnd),
monad: Monad,
uall: ∀[x:A]. B[x],
member: t ∈ T,
apply: f a,
isect: ⋂x:A. B[x],
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
monad: Monad,
M-return: M-return(Mnd),
M-map: M-map(mnd),
pi1: fst(t),
pi2: snd(t)
