Keep in mind that you have to invest some time in learning Haskell
before you can reap the benefits. For an example of the latter, see also
Paul Hudak, Mark P. Jones.

In a sense, you have to learn programming anew.

A key philosophy of Haskell compared to other functional programming
languages like OCaml or Clojure is that Haskell is pure , i.e.
functions do not have side-effects. Incidentally, purity is the only way
to implement software transactional memory with the proper static
