Nuprl Lemma : lifting-apply-callbyvalueall

[a,B,c:Top].  (let x ⟵ in B[x] let x ⟵ in B[x] c)


Proof




Definitions occuring in Statement :  callbyvalueall: callbyvalueall uall: [x:A]. B[x] top: Top so_apply: x[s] apply: a sqequal: t
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T so_lambda: so_lambda(x,y,z,w.t[x; y; z; w]) so_apply: x[s1;s2;s3;s4] top: Top uimplies: supposing a strict4: strict4(F) and: P ∧ Q all: x:A. B[x] implies:  Q has-value: (a)↓ prop: guard: {T} or: P ∨ Q squash: T so_lambda: λ2x.t[x] so_apply: x[s]
