Re: [Haskell-beginners] Defining an instance: Syntax that works exactly sometimes

Should I always look first in the 98 Report, and only if I don't find something there then look in the User's Guide? Should I always look through both, lest something in the 98 Report be obsolete? Is nothing in it obsolete? On Thu, Jan 22, 2015 at 7:40 PM, Brandon Allbery wrote:

I have not found the "deriving" keyword's specification anywhere.

The correct place to look for this and other things, including instances, is the Haskell Report.
