Hi.
During a tentative (quite unsuccessfull) to convert a simple Python
script that prints on stdout a directory and all its subdirectory [1] in
a good Haskell (mostly to start to do real practice with the language),
I came across this blog post:
http://blog.moertel.com/articles/2007/03/28/directory-tree-printing-in-haskell-part-three-lazy-i-o
Since recently I read about alternatives to lazy IO (like iteratee), I'm
curious to know if a flexible, efficient and safe alternative exists,
for the task of display a directory tree.
