Hi, I try to undestand why this code dosen't work f :: (Num a)=>Integer->a f i = i
as for every beginner which tries to grok type classes, i recommend you to read http://haskell.org/haskellwiki/OOP_vs_type_classes and especially papers mentioned there in References section also, i recommend you to subscribe to ru_declarative and ru_lambda LiveJournal communities and read them back - several month ago i've placed there simple explanation of differences between C++ templates, OOP classes and Haskell type classes -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
