+-- A set of convenient combinators of effectful actions for building handlers
+-- and services tuned for special purposes.
+
+-- | Runs an effectful computation and then returns an empty 'L.ByteString'
+--
+-- This combinator saves printing the final @return L.empty@ action in handlers
+-- that return unused or empty 'L.ByteString'.
+--
+-- For example, handler /signalUpconf/ being declared as an
+-- [/update callback/](https://github.com/lyokha/nginx-haskell-module#update-callbacks)
+-- in
+--
+-- @
+-- type Upconf = [Text]

+-- returns an empty bytestring which is not used in a meaningful way, therefore
+-- it can be rewritten as
+--
+-- @
+-- signalUpconf :: Upconf -> Bool -> IO L.ByteString
+-- signalUpconf = const . __/voidHandler/__ . mapConcurrently_ getUrl
+-- @
+--
+-- which helps to focus better on the computation itself.
