GHC plays fast and looose with the Haskell 2010 prelude. Two examples:

GHC drops Eq from the context of class Num.

GHC introduces class Applicative.

You will stumble over such discrepancies if you try to write or
read GHC code as if it were Haskell 2010.

>  I  think that’s a little unfair to GHC 😊. If you don't give any language extension flags you get Haskell 98 -- or nowadays Haskell 2010.
