WebNov 22, 2008 · Tail-call optimization is where you are able to avoid allocating a new stack frame for a function because the calling function will simply return the value that it gets from the called function. The most common use is tail-recursion, where a recursive function written to take advantage of tail-call optimization can use constant stack space. Web2.3.1 Predefined List Loops. In addition to simple operations like append, Racket includes functions that iterate over the elements of a list.These iteration functions play a role similar to for in Java, Racket, and other languages.
