Nuprl Lemma : bag_qinc
∀A:Type. ((A List) ⊆r bag(A))
Proof
Definitions occuring in Statement : 
bag: bag(T)
, 
list: T List
, 
subtype_rel: A ⊆r B
, 
all: ∀x:A. B[x]
, 
universe: Type
Definitions unfolded in proof : 
bag: bag(T)
, 
all: ∀x:A. B[x]
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
so_lambda: λ2x y.t[x; y]
, 
so_apply: x[s1;s2]
, 
uimplies: b supposing a
