[Haskell-cafe] Small question

Which of these is likely to go faster? type Quad = (Bool,Bool) foo (r,t) = let x = if r ... y = if t ... in ... data Quad = BL | BR | TL | TR foo q = let x = if q == TL | q == TR ... y = if q == BR | q == TR ... in ... (Unless somebody has a better idea...) I'm hoping that the latter one will more more strict / use less space. But I don't truely know...
