[Haskell-cafe] Introspection

Is it possible to access type information and perform either of the following in a Haskell program? 1) Find the type/class of a variable e.g. a type predicate: is y of-type A, or is y of-Class A 2) Assert the type of a variable e.g. if y.length > 100 then y is of type big.
