Agreed, but how are package maintainers supposed to find out problems
early without much hassle? For my part, I am using Travis CI, but
AFAICT it supports only GHC 7.4.1
(https://github.com/travis-ci/travis-ci/issues/882). There might be
some cruel hacks like downloading some binary builds from somewhere
etc., but this is not a real solution and takes ages.

It would be very cool if Travis CI supported multiple GHC versions,
including a version close to HEAD.
