[Haskell-beginners] Fwd: Real World Haskell: From Portable to System.Win32

[Paulo M. Pocinho]

createFile is probably what I should be looking for. 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!
