Hi Haskellers, I've recently found myself using the expression: "foldr (.) id" to compose a list (or Foldable) of functions. It's especially useful when I need to map a function over the list before composing. Does this function, or the more general "foldr fmap id", defined in a library anywhere? I googled and hoogled, but no luck so far. Thanks, Greg
