... However, there’s another way of stating the evaluation rules that is more elegant, and indeed more standard for the lambda calculus. It doesn’t involve function closures, but instead uses substitution. The key idea is that we’d like to regard (λx.e1 ) e2 as equivalent to e1 where e2 is substituted f ...
