BTW,

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

  c) Put it into containers -- probably a -1 because it would force a
     containers dependency where there was no containers dependency before.

Any other ideas?
