1 hint
=====================================================================
Note: to ignore a particular hint (e.g. "Reduce duplication"), write
this in the source file:
{-# ANN module ("HLint: ignore Reduce duplication" :: Text) #-}
You can also apply it just to a particular function, which is better:
{-# ANN funcName ("HLint: ignore Reduce duplication" :: Text) #-}
