There is a package system-filepath http://hackage.haskell.org/package/system-filepath which fixes a lot of quibbles people have with the way filepaths are implemented in haskell. There are apparently a lot of problems with using strings as filepaths, like the fact that they are slow, that they have encoding issues, and that people cannot make a path that is system agnostic.

So the </> operator in that library just joins two filepaths together with the correct slash.

Wait, what? Where'd "</>" come from?
