An issue that needs to be resolved is: "Where should this change go?" We have a couple of options:

a) Bring http://hackage.haskell.org/package/hashable into the platform

b) Put the module into base -- probably a -1 for political/logistical reasons

I'd say base

I would suggest not putting it into base if it isn't necessary to do so. It's much easier to merge things later (if desired) than to split them apart, and base is already far too big.

+1. Especially given the recent trend towards breaking things out of base, moving this in is suspect. As folks have been moving towards base-4 we've been able to finally start getting rid of the slew of Cabal flags for figuring out when base does or does not include various libraries. Don't start inventing new ones :) -- Live well, ~wren
