Nuprl Lemma : C_LVALUE-definition
∀[A:Type]. ∀[R:A ─→ C_LVALUE() ─→ ℙ].
((∀loc:C_LOCATION(). {x:A| R[x;LV_Ground(loc)]} )
⇒ (∀lval:C_LVALUE(). ∀idx:ℤ. ({x:A| R[x;lval]} ⇒ {x:A| R[x;LV_Index(lval;idx)]} ))
⇒ (∀lval:C_LVALUE(). ∀comp:Atom. ({x:A| R[x;lval]} ⇒ {x:A| R[x;LV_Scomp(lval;comp)]} ))
⇒ {∀v:C_LVALUE(). {x:A| R[x;v]} })
