As a side note, I really think this is not a big deal. The portable code is a lot better. I wonder if that exercise was a pun on working with Haskell code just to step back into foul territory. And yes, extra careful on the parameters, or it may end up corrupting other files, launch the missiles and whatnot. One thing I noticed so far using Haskell, usually I have to spend more time thinking before hitting the keyboard. Yet the code is always elegant. Meanwhile, I've been taking a peek inside System.IO.HVFS from MissingH [1]. Looks nice. Thanks for the replies. Cheers! -- [1] http://hackage.haskell.org/packages/archive/MissingH/1.1.1.0/doc/html/System-IO-HVFS.html#v:vGetModificationTime On 8 October 2011 20:34, Henk-Jan van Tuyl <hjgt...@chello.nl> wrote: > On Sat, 08 Oct 2011 18:45:43 +0200, Chadda?
