∀[T:Type]. ∀[as,bs:T List].  (eager-append(as;bs) ∈ T List)
Proof
Definitions occuring in Statement : 
eager-append: eager-append(as;bs)
, 
list: T List
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
universe: Type
Definitions unfolded in proof : 
eager-append: eager-append(as;bs)
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
so_lambda: so_lambda(x,y,z.t[x; y; z])
, 
has-value: (a)↓
, 
uimplies: b supposing a
, 
so_apply: x[s1;s2;s3]
