Possibly Hugs bug, or possible GHCi feature?

 {{{
 showln  = (++ "\n") . show
 main    = interact (showln . length)
 }}}

 In GHCi:
 {{{
 $ ghci Z.hs
 *Main> :t showln
 showln :: Int -> [Char]
 }}}

 In Hugs (Version: March 2005):
 {{{
 ERROR "Z.hs":1 - Unresolved top-level overloading
 *** Binding             : showln
 *** Outstanding context : Show b
 }}}

 I'm not sure which is right.
