The vector-random package regression
I'm not sure if this is a recent regression but I just installed the Haskell Platfom 2012.2. The email for the maintainer dons@galois.com (Don Stewart) no longer seems to be valid. Dominic.

As far as I know, earlier versions of GHC didn't check for unused INLINE pragmas.

That was relatively easy to fix but I don't think I can submit a patch as there is no repository for the code and the email of the maintainer is no longer valid. I am probably using the package incorrectly but worse, for some types it does not seem to generate random values - see below. I don't think there's anyway of submitting a bug report; I'm reporting it here so there is at least some awareness there might be a problem. Dominic.

That reminds me of: http://search.dilbert.com/comic/Random%20Number%20Generator (sorry if this off-topic post offends anyone on this otherwise serious list) Best regards, Krzysztof Skrzętnicki On Sat, Jun 16, 2012 at 1:52 PM, Dominic Steinitz < idontgetoutmuch@googlemail.com> wrote:
