It is possible to define directly the lazy reduction, as shown in the next definition. Definition 2.2 i) The β-rule is defined as (λx.M)N → M[N/x]. ii) The β-reduction is the contextual closure of the β-rule. We will denote

That, however, is not necessarily the most efficient method, given that the quotient from the division is not really required …
