Comment(by rl):

 To be honest, neither of these is particularly pleasing. A 20% performance
 hit is quite bad, though. If you show me the benchmark where this happens,
 I'll try to see what I can do about it. Perhaps there is a better
 solution, such as fixing GHC to generate better code here. If all else
 fails, we'll have to do something like what you suggest but I'd much
 prefer something higher-level.
