Nuprl Lemma : strictness-callbyvalue

∀[F:Top]. (eval x = ⊥ in F[x] ~ ⊥)


Proof




Definitions occuring in Statement :  bottom: ⊥,  callbyvalue: callbyvalue,  uall: ∀[x:A]. B[x],  top: Top,  so_apply: x[s],  sqequal: s ~ t
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  has-value: (a)↓,  not: ¬A,  implies: P ⇒ Q,  false: False,  top: Top
