...this seemed not to make it to the mailing list (ghc-users@haskell.org isn't valid)... -- Hal Daume III "Computer science is no more about computers | hdaume@isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume ---------- Forwarded message ---------- Date: Wed, 11 Dec 2002 08:33:50 -0800 (PST) From: Hal Daume III To: Simon Peyton-Jones Cc: ghc-users@haskell.org, Kirsten Chevalier Subject: Re: Constructors in GHC Hi, It finally makes sense now :)

We could make this more consistent in two ways. Alternative (A): One way would be to make it clearer that $wMkT was the real constructor:

data T = $wMkT Int Int MkT p = case p of (x,y) -> $wMkT x y f x y = $wMkT x y g t = case t of $wMkT x y -> x

Alternative (B): The other alternative would be to make the original Haskell constructors into the $w things:

data T = MkT Int Int $wMkT p = case p of (x,y) -> MkT x y f x y = MkT x y g t = case t of MkT x y -> x

As someone using external core, I can resoundly say: I don't really care :). I would probably prefer (B), as you seem to, but it's not a strong preference.
