Thanks for your feedback, I'll be sure to make it explicit from the User
Manual that Metal is tested on newer compiler versions as well [1].

I think in the particular case of C++ on Travis CI it is kind of implicit
that you should take care of installing whatever development tools fit your
needs. To make this easy for the developer, they make it possible for the
user to specify 'sudo: required', which basically provides easy access to
the various package repositories available to Ubuntu. Alternatively, the
user can give up on administrator rights in exchange for better hardware
and faster builds, but in this case one must request repositories and
packages to be whitelisted by the Travis team [2], [3], [4], which is often

For an example of how to set up Travis to test on several versions of GCC
and Clang, you can take a look at Metal's '.travis.yml' [5], although there
are plenty of other good examples out there, for instance you can also
check Boost.Hana and Metabench.
