Pattern Matching - Making the Compiler Work For You Â· deliberate software
Pattern matching is a simple tool that will make your code safer and easier to read. Consider the following code that converts an Int to a string. public enum Language { Spanish, English } public static string convert(int number, Language lang) { string ret = ""; if (lang == Language.English) { switch(number) { case 0: ret = "zero"; break; case 1: ret = "one"; break; default: ret = "..."; break; }

Pattern guard - HaskellWiki
Haskell 2010 changes the syntax for guards by replacing the use of a single condition with a list of qualifiers. These qualifiers, which include both conditions and pattern guards of the form pat <- exp, serve to bind/match patterns against expressions. The syntax is comparable that of a list comprehension, where instead the types of pat and exp match. This makes it easy, for instance, to pattern
