Description:
fold function for Bool type; documentation
Function `bool' allows folding over boolean values, that is comparable to the `maybe' or `either' functions on their respective types. . Function `bool' is a replacement for the build-in if-then-else syntax. However, since it is a function, it can be partially applied and passed around to higher order functions. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
