Nuprl Lemma : lifting-callbyvalueall-pair

∀[a,b,B:Top].  (let x ⟵ <a, b> in B[x] ~ let x ⟵ a in let y ⟵ b in B[<x, y>])


Proof




Definitions occuring in Statement :  callbyvalueall: callbyvalueall,  uall: ∀[x:A]. B[x],  top: Top,  so_apply: x[s],  pair: <a, b>,  sqequal: s ~ t
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  callbyvalueall: callbyvalueall,  evalall: evalall(t),  top: Top,  all: ∀x:A. B[x],  implies: P ⇒ Q,  has-value: (a)↓,  prop: ℙ
