[Haskell] Views in Haskell

[Pablo Nogueira]

Just a quick note

In the very first example (function f), the comment should say "f [n]"
insteand of "f [x]"

In the related work, the "Active Patterns" proposal by Palao et at is missing:

http://portal.acm.org/citation.cfm?id=232641&coll=portal&dl=ACM

I thought this work should be included in the list because, I believe,
they were the first to point out that computation should take place
before matching, which was not the case in Wadler's and Burton's
proposals?  They also proposed  types for patterns.
