Continuing the above example, if, in the universe of types , there is a type and a family of types , then there is a dependent pair type. In mathematics and computer science, mutual recursion is a form of recursion where two or more mathematical or computational objects, such as functions or datatypes, are defined in terms of each other [1] mutual recursion is very common in functional programming and in some problem domains, such as recursive descent parsers, where the datatypes are naturally mutually recursive. Laurie williams is an american software engineer known for her writings on pair programming and agile software development
