Hello, I hope that it does but I have not installed GHC 6.12 yet. I was wondering more how to write new programs that are not restricted to work only with GHC >= 6.12.1. Sometimes one can make things portable with a bit of CPP---not pretty but it works---but, in this case, I could not think of a good way to do this, so if anyone has ideas...
-Iavor PS: I sympathize with the desire to avoid having two ways of doing the same thing in the long run, but it would have been nice to have both features in an official release so that we could compare them both in practice before the one got deprecated.
