On the surface, Haskell would appear to not offer reflection. However, you can get quite a long way with Data.Generics and Data.Dynamic, and deriving (Typeable, Data), which will give you introspection of data types. Here's a nice little article on using deriving Data: http://www.defmacro.org/ramblings/haskell-web.html And the hs-plugins library will give you dynamic loading, but I don't think there's any introspection capability (yet?)
