* Package name : haskell-type-level Version : 0.2.4 Upstream Author : Alfonso Acosta, Oleg Kiselyov, Wolfgang Jeltsch et al * URL : http://hackage.haskell.org/cgi-bin/hackage-scripts/package/type-level * License : BSD Programming Lang: Haskell Description : A Haskell library for type-level programming A haskell library for performing computations on the type-level. Type-level functions are implemented using functional dependencies of multi parameter type classes. To date, Booleans and Numerals (Naturals and Positives) are supported. With regard to Numerals, there is support for common arithmetic operations (addition, substraction, multiplication, division, exponientation, logarithm, maximum, comparison, GCD) over natural numbers (using a decimal representation to make compile-time errors friendlier). Although making use of type-level computations might seem devious and obfuscated at first sight, it is indeed useful in practice to implement lightweight dependent types such as number-parameterized types (e.g. an array type parameterized by the array's size or a modular group type Zn parameterized by the modulus). -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
