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...
