Nuprl Lemma : Message-inhabited
∀[f:Name ⟶ Type]. ↓Message(f) supposing ↓∃h:Name. (↓f h)
Proof
Definitions occuring in Statement : 
Message: Message(f)
, 
name: Name
, 
uimplies: b supposing a
, 
uall: ∀[x:A]. B[x]
, 
exists: ∃x:A. B[x]
, 
squash: ↓T
, 
apply: f a
, 
function: x:A ⟶ B[x]
, 
universe: Type
Definitions unfolded in proof :
