Nuprl Lemma : cond-verify-msg-body_wf
∀[f:Name ⟶ Type]. ∀[T:Type]. ∀[hdr:Name]. ∀[msg:Message(f)].
cond-verify-msg-body(hdr;msg) ∈ bag(T) supposing hdr encodes T
Proof
Definitions occuring in Statement :
cond-verify-msg-body: cond-verify-msg-body(hdr;msg),
encodes-msg-type: hdr encodes T,
Message: Message(f),
name: Name,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
cond-verify-msg-body: cond-verify-msg-body(hdr;msg),
all: ∀x:A. B[x],
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
uiff: uiff(P;Q),
and: P ∧ Q,
ifthenelse: if b then t else f fi ,
bfalse: ff
