Hello,
I don't know exactly which of the following questions have already been
answered but I decided to answer them all anyway.

My Haskell experiments have reached a size in which debugging tools would be
more than welcome, so I looked around, and was very disappointed. I tried
Hood, which is a pain to use (lots of editing of the code required), I looked
at Buddha but didn't want to downgrade to GHC 5 for trying it (nor

If your code goes out to far right, it's a good idea to
make a function out of it.

Code should be formatted in a way easy to scan
Hi,
I have problems finding a pleasing indentation style for haskell code.
Especially nested do-blocks have a tendency to run away to the right margin.
When looking on source code from experienced haskell programmers, there
seems not to be any consensus at all, everyone uses their own convention

Can be written simpler
puzzle = (!!) $ iterate (s (
