type</emphasis>. For example:
data T a where { T1 { f1::a, f2::(a,b) } :: T a } -- b is existential
upd1 t x = t { f1=x } -- OK: upd1 :: T a -> b -> T b
upd2 t x = t { f2=x } -- BAD (f2's type mentions b, which is
- existentially quantified)
+ -- existentially quantified)
data G a b where { G1 { g1::a, g2::c } :: G a [c] }
upd3 g x = g { g1=x } -- OK: upd3 :: G a b -> c -> G c b
