The solution would be to bring 'sum' and 'product' into the Num class so the most efficient version for each type can be used and the default is no worse than the current non-class versions. (this is even pretty much completly backwards compatable so could be considered for haskell 06)
I'd also like to see 'join' and 'ap' added to Monad while we are at it.

Ooo, that's much better. I'll retract my sum' suggestion in that case.
