[Haskell-cafe] introducing Maybe at managing level

[luc taesch]

I was looking for some link introducing the way FP/ Haskell handles 
errors and Exceptions.

This is for a non FP Guy, and ideally withought scaring them with 
Monads and category theory :-).

for the background :

the guy said : As I mentioned in another thread in banking (in 
particular) it is the exception processing that often dominates the 
functionality of a system - as the core concept is generally very 
straightforward. Developing for "exception handling" (not in a Java/C++ 
sense) is a tricky thing - as the exception don't necessarily shout 
themselves out - and are often why we have large misunderstood legacy 
systems which are hard to replace.
