Re: [Haskell-beginners] type signature error in a where clause

Right, sorry I should have tested :) I guess ScopedTypeVariables allows the forall keyword too, like myriad of other extensions ? (In my opinion, this extension should really be part of the Haskell standard, it's pretty useful, though not indispensable) On Sat, Nov 24, 2012 at 4:00 PM, Brandon Allbery wrote:

Note that you'll need to authorize the use of the forall keywords by adding :

{-# LANGUAGE ExplicitForall #-}

to the beginning of your file.

I think you forgot {-# LANGUAGE ScopedTypeVariables #-} ?
