I had been considering Haskell a value-oriented language and had concluded that doing a lot of file system actions would be cumbersome. Dons, put that all to rest:

metaperl: dons - if you are doing a lot of file-system manipulation, doesnt using a value-oriented language like Haskell become cumbersome? metaperl: dons - i mean things like copying files, renaming files, etc dons: metaperl: hmm, like darcs? dons: why? you're using a first-class action oriented language too, remember metaperl didn't think of darcs dons: so you can string together your manipulting functions in interesting ways dons: i.e. haskell treats imperative statements as first class citizens dons: you can pass them to functions, put them in data structures dons: map over them dons: > sequence_ $ reverse [readFile "/tmp/x", writeFile "/tmp/y"]

wow. Haskell wins again.

and mkcabal.hs is a prime example of scripting and file system operations in Haskell..
