Comment(by igloo):
Oh, I missed this comment in your previous message:
> We will have to separately sort out the pretty package needs to change
if it wants to use the `Data.Monoid.(<>)` operator.
Surely having a single GHC release in which `Data.Monoid` and
`Text.PrettyPrint` have conflicting definitions of `<>` is the worst case?
Anyone importing both will need to change their code to disambiguate in
order to work around a transient problem.
Why not just make both changes at once, with GHC 7.6.1? This could be done
in the HEAD now, and should be released well under a year after 7.4.1.
