Comment (by ekmett):

 FWIW- The committee is in favor of adding the `Generic`, `Generic1`,
 `Data` and `Typeable` instances along with `Num` for `Sum` and `Product`.

 Do we want to try to pester Austin at the 11th hour to add them to the 7.8
 release candidate or hold off a year for 7.10?

 The former has the benefit of, well, being a year sooner, but it may be
 that that ship has already sailed.

 Moreover, it'd means you can't write code that needs those instances and
 which works with both the 7.8.1-release candidates and the final release.

 On the other hand, once we have 7.8.1 the release candidates will have
 done their job and will be a non-issue.

 At this point I defer to Austin about the viability of packaging it up now
 or if we should wait.
