What's the advantage of using if/else over case of

[PiotrJustyna]

Here is what hlint suggests:

app/LayoutEngine.hs:(71,9)-(75,22): Suggestion: Use if
Found:
  case Records.getIconName i `elem` namesOfDependentIcons of
    True
      -> let newPositionedIcon = toPositionedIconWithParent i parent
         in
           newPositionedIcon
             : (firstLineDependents newPositionedIcon dependencyPlane) ++ acc
    False -> acc
Perhaps:
  (if Records.getIconName i `elem` namesOfDependentIcons then
       (let newPositionedIcon = toPositionedIconWithParent i parent
        in
          newPositionedIcon
            : (firstLineDependents newPositionedIcon dependencyPlane) ++ acc)
   else
       acc)
