'choice' in Control.Applicative?

[Greg Fitzgerald]

Should there be a 'choice' function in Control.Applicative?

choice :: Alternative<http://www.haskell.org/ghc/docs/latest/html/libraries/base/Control-Applicative.html#t%3AAlternative>f
=> [f a] -> f a
choice = foldr (<|>) empty
or:
choice = Data.Foldable.asum

Thanks,
Greg
