| in general, it's too complex problem, otherwise Simons may already work | on it, because current ghc-generated code is, say, 3 times slower than | it could be. Thank you for believing in our expertise, but you should not assume that something we have not done is necessarily very difficult. GHC has a huge surface area these days, so we spend a lot of time just keeping everything working. Then we are researchers too (e.g. Simon M is on the ICFP program committee) -- maintaining GHC isn't even our real job. As a result there are many not-very-hard jobs that we simply do not get around to. (I don't know if this is one of them, though.) So I say an enthusiastic Yes to anyone who's willing to jump in and start helping. We need more people familiar with GHC's innards. Simon
