I've just started playing around in Haskell. After years of Ruby, I got used to a file organization that's used by Ruby on Rails or Rugui.
Are there any guidelines, best practices, or maybe even frameworks about file-organization in Haskell programs?
("Learn you a Haskell" & "Real World Haskell" don't really handle this issue.)
haskell.org defines two file and directory layouts that may be helpful, along with some tool guidance.
