Ok, ok, I tend to forget that Haskell lists are lazy streams, not just
simple stacks... which makes them indeed a /lot/ more useful than the
corresponding data type in strict languages.
I still think all those nice short and meaningful names in the Prelude
(map, filter, ...) should be type class members in some suitable
standard collection library.
