only it isn't. That's a property of a shell, the underlying OS allows spaces in file names with no need for an escaping mechanism.

Okay, that was a mistake... but it does not change the point, that pathToString needs to work out what platform it is on, and doing it without typeclasses makes it not extensible. We need a way of allowing people to define new path printers (as members of a class)... whilst having the program determine which platform it is on, and choosing the correct instance (at compile time).
