Re: [Haskell-cafe] GHC.Generics and newtypes

Sorry, I wasn't clear. What I want is somehow to find out whether the type under consideration is declared using data or newtype. Is it possible? Roman * José Pedro Magalhães [2013-01-27 20:29:52+0000]

Hi Roman,

Yes, the automatic derivation of Generic instances does not see through newtypes.

Cheers, Pedro

Hi,

Is it possible to generate different instances for newtypes and datatypes using GHC.Generics?
