Re: [Haskell-cafe] Profiling nested case

2008/7/12 Mitar :

So that I can easily change the type everywhere. But it would be much nicer to write:

data Quaternion a = Q !a !a !a !a deriving (Eq,Show)

Only the performance of Num instance functions of Quaternion is then quite worse.

You can probably use a specialization pragma to get around that. -- Jedaï
