- pattern matching — 1. A function is defined to take arguments of a particular type, form or value. When applying the function to its actual arguments it is necessary to match the type, form or value of the actual arguments against the formal arguments in some definition. For example, the function length [] = 0 length (x:xs) = 1 + length xs uses pattern matching in its argument to distinguish a null list from a non-null one. There are well known algorithm for translating pattern matching into conditional expressions such as "if" or "case". E.g. the above function could be transformed to 2.

- peano arithmetic — (mathematics) Giuseppe Peano's system for representing natural numbers inductively using only two symbols, "0" (zero) and "S" (successor). This system could be expressed as a recursive data type with the following Haskell definition: data Peano = Zero | Succ Peano The number three, usually written "SSS0", would be Succ (Succ (Succ Zero)). Addition of Peano numbers can be expressed as a simple syntactic transformation: plus Zero n = n plus (Succ m) n = Succ (plus m n) (1995-03-28)
