 It's possible to build a logical system equally powerful as the lambda calculus (and readily intertranslatable with it) using just combinators, considered as atomic operations. Such a language doesn't have any variables in it: not just no free variables, but no variables at all.

 For instance, Szabolcsi argues that reflexive pronouns are argument
 duplicators.

+Notice that the semantic value of *himself* is exactly W.
+The reflexive pronoun in direct object position combines first with the transitive verb (through compositional magic we won't go into here).  The result is an intransitive verb phrase that takes a subject argument, duplicates that argument, and feeds the two copies to the transitive verb meaning.

 These systems are Turing complete. In other words: every computation we know how to describe can be represented in a logical system consisting of only a single primitive operation!
