WitrynaCall-by-value and call-by-reference make the most sense in a language with a value model of variables: they determine whether we copy the variable or pass an alias for it. Neither option really makes sense in a language like Smalltalk, Lisp, ML, or Clu, in which a variable is already a reference. WitrynaCall-by-value and call-by-name both use the same rules of reduction, but in different places and in a different order. In your case the call-by-value and call-by-name do not differ, because the arguments are already reduced. Here is an example, where the difference matters. Reduce (λpq.pqp)((λab.a)(λcd.d))
