[Haskell-beginners] tuple space

[Mike Houghton]

In Java
List<T> ensures all entries are of type T  - so only one type allowed.
List<Object> allows anything but you lose type safety.

HList allows anything and retains the types. (but you do get a lot of <<< >>>>>> in declarations :) and really its pushing Java into something it isn’t. )
