This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
HoleyMonoid allows building monoidal values of which certain components are to be filled in later. For example:
> let holey :: (Show a, Show b) => HoleyMonoid String r (a -> b -> r) holey = now "x = " . later show . now ", y = " . later show > run holey 3 5 "x = 3, y = 5"
