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
