Nuprl Lemma : once-class_wf
∀[Info,A:Type]. ∀[X:EClass(A)]. ((X once) ∈ EClass(A))
Proof
Definitions occuring in Statement :
once-class: (X once),
eclass: EClass(A[eo; e]),
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
once-class: (X once),
subtype_rel: A ⊆r B,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
uimplies: b supposing a,
all: ∀x:A. B[x],
