Re: [Haskell-beginners] Named fields in data types

Excerpts from legajid's message of Wed Nov 18 15:11:01 -0500 2009:

I've tried these lines : contact01 = Adresse "Didier" 51100 "Reims" contact02 = Adresse {nom="Laure", cp=0} contact02 = contact02 { ville="Nogent" }

but i get an error : multiple declarations of Main.contact02 So, does it mean i can't add values to contact02. Instead, i must create a contact03 based on contact02 ?

Yep; part of the point behind a pure functional language is to not allow mutation by default. Cheers, Edward
