[Haskell-cafe] How to get a list of constructors for a type?

Say I have something like

data DT a = Foo a | Bar a | Boo a

I want something like a list of the constructors of DT, perhaps as [TypeRep].  I'm using Data.Typeable but can't seem to find what I need in there.  Everything there operates over constructors, not types.
