Type-Indexed Data Types

open access: yesScience of Computer Programming, 2002
AbstractA polytypic function is a function that can be instantiated on many data types to obtain data type specific functionality. Examples of polytypic functions are the functions that can be derived in Haskell, such as show, read, and ‘==’. More advanced examples are functions for digital searching, pattern matching, unification, rewriting, and ...
