Is it possible to force-show (i.e., create a string representation) an arbitrary record in PureScript for debugging purpose regardless of it having a type-class instance for `Show`? 

I would like to show the contents of the [Pux Event](http://www.alexmingoia.com/purescript-pux/docs/API/Pux/Html/Events.html#) object but it does not have a Show instance:

```
  No type class instance was found for

    Data.Show.Show { target :: { value :: String
                               , checked :: Boolean
                               }
                   , currentTarget :: { value :: String
                                      , checked :: Boolean
                                      }
                   , altKey :: Boolean
                   , button :: Number
                   , buttons :: Number
                   , clientX :: Number
                   , clientY :: Number
                   , ctrlKey :: Boolean
                   , metaKey :: Boolean
                   , pageX :: Number
                   , pageY :: Number
                   , screenX :: Number
                   , screenY :: Number
                   , shiftKey :: Boolean
                   }
