haskell - Multiple declarations of 'MyModule.myTypeclassFunction' -

-

in main.hs

class aable     getname :: aable → string  class b bable     getname :: bable → string

returns compilation error leksah/ghc

src\main.hs:23:4:     multiple declarations of `main.getname'     declared at: src\main.hs:20:4                  src\main.hs:23:4

i need both able return name, different signification in both cases. should declare class , b in 2 different modules ?

kneejerk reaction: use show. reading better, see want propably different semantically (despite identical type signatures). why not use different name? descriptiona , descriptionb perhaps? declaring them in different modules solve compilation error, (1) still have 2 different things same name , (2) whenever import both modules (unqualified), you'll same error.
