[Haskell-cafe] Parsec: Where's +++?

Koen Claessen's "Parallel Parsing Processes," suggests their parsing combinators have been integrated into Parsec. If so, where is the +++ operator hiding? If not, does anyone know of a parsing library with a choice operator that does breadth-first search? Also, how do I determine what instances a datatype supports? Is Parsec an instance of Applicative? Thanks, Greg
