PS: An effect of having this instance made default in Prelude is that
    GHCi would show a somewhat different result in some cases (not sure
    though if this a good or bad thing):


      GHCi, version 7.8.3: http://www.haskell.org/ghc/  :? for help
      Loading package ghc-prim ... linking ... done.
      Loading package integer-gmp ... linking ... done.
      Loading package base ... linking ... done.
      λ:2> id
       
      <interactive>:2:1:
          No instance for (Show (a0 -> a0)) arising from a use of ‘print’
          In a stmt of an interactive GHCi command: print it
      λ:3> import Text.Show.Functions
      λ:4> id
      <function>
      it :: a -> a
