Tail-call optimization (TCO) allows programmers to write interesting tail-recursive functions without worry of overflowing the program's stack memory. In languages that require constant space tail calls (i.e. Scheme and Standard ML), recursion becomes a natural and efficient way to express iteration. In this talk we discuss a method to extend Clojure's TCO support for arbitrary mutual recursion via well-known code transformations including CPS and trampolining, and how these transformations enable more succinct and clear programming. We also examine a source-to-source compiler that applies these transformations, having minimal impact on the performance of the generated code and allowing interoperability with non-CTCO Clojure programs.
