Tail recursion is important to some high-level languages, especially functional and logic languages and members of the Lisp family. In these languages, tail recursion is the most commonly used way (and sometimes the only way available) of implementing iteration. The language specification of Scheme requires that tail calls are to be optimized so as not to grow the stack. Tail calls can be made explicitly in Perl, with a variant of the "goto" statement that takes a function name: goto &N… Web] [ Also need to implement tail recursion somewhere early, and fwd ref the chapter go recursion. ] In this section I'll demonstrate the most common idioms for recursive over simple data structures--lists and trees.
