[Haskell-cafe] Haskell overview

[Mark Carroll]

A colleague with a mathematics and Lisp background is wanting to learn
more about Haskell. The books he's looked at concentrate more on building
up from the basics and getting the syntax right, etc., whereas really he's
looking more of a top-down view that makes Haskell's features and behavior
clear and relates them to category theory, etc. Would anyone be able to
suggest some good references?
