Here's how I think:

1. The decision to not go with 7.2 was not bad.  I think upstream
   caused a bit of confusion by giving a stable-release-number to a
   tech preview.
2. I think the correct path forward is to drop HP.  HP is a set of
   libraries, and it blesses certain versions of those libraries.
   Each of those libraries is however released independently as well
   so sticking with HP feels counter to how the Arch Way is
3. My impression was that there was a majority of people on the
   ArchHaskell mailing list in favour of dropping HP.

There's still a bit of work needed to keep up with HP since there's
been a new release with GHC 7.0.4.


[1]: I write it this way since I can't find anything in the Arch Way
saying that it's a goal to always stay with the latest release of

Perl is another example of filling a tiny, short-term need, and then
being a real problem in the longer term.
