Re: [Haskell-cafe] ANNOUNCE: Haskell BOF on 29c3 in Hamburg, Germany
Hey, sounds interesting, I'll be there :) Also, HTML in the description doesn't seem to work, you might want to add the links as footnotes or something. Koomi ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Non polymorphic numerals option -- avoiding type classes
You should note that GHCi uses extended defaulting rules as explained in [1]. This means that a literal like 5 will only be of type Num a = a in GHCi while in a normal Haskell program it will default to some concrete type (Integer if there are no other constraints). Also, if you define x = 5 in a .hs file and load the file in GHCi, x will have type Integer. In my short search I could not find out how to reverse this behavior, :unset -XExtendedDefaultRules does not seem to work. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
