Hey list, I'm currently using :set -Wall in my .ghci to enforce some good coding practices on my side. Something like missing type signatures and the like. It has saved me quite a lot of hassle over the last couple of days as I experimented more with Haskell. But it seems, -Wall may be just a little too… overzealous: Prelude> 2^2 Warning: Defaulting the following constraint(s) to type `Integer' `Num t' arising from a use of `^' at <interactive>:1:0-2 Warning: Defaulting the following constraint(s) to type `Integer' `Integral t' arising from a use of `^' at <interactive>:1:0-2 Warning: Defaulting the following constraint(s) to type `Integer' `Num t' arising from a use of `^' at <interactive>:1:0-2 Warning: Defaulting the following constraint(s) to type `Integer' `Integral t' arising from a use of `^' at <interactive>:1:0-2 4 (I've shortened ghci's response a bit) So, do you have a good (recommended) set of -W switches for a newbie playing around in GHCi, so I can learn a good style? Forgive me if it's somewhere on page one of some book or tutorials - I've read so many of both, I'm beginning to forget things. Thanks, Aleks
