Proof
Definitions occuring in Statement :
MMTree_Leaf: MMTree_Leaf(val),
MMTree: MMTree(T),
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type

member: t ∈ T,
MMTree: MMTree(T),
MMTree_Leaf: MMTree_Leaf(val),
eq_atom: x =a y,
ifthenelse: if b then t else f fi ,
btrue: tt,
subtype_rel: A ⊆r B,
ext-eq: A ≡ B,
and: P ∧ Q,

has-value: (a)↓,
nat: ℕ,
le: A ≤ B,
less_than': less_than'(a;b),
false: False,
not: ¬A,
implies: P ⇒ Q,
