--- Comment #4 from Johel Ernesto Guerrero Peña <johelegp at gmail dot com> --- With the setup in Comment 3, now I can also include `<chrono>` in the GMF of a module. I don't think this worked last week. Though all I'm doing in the module is specializing a my-library type trait on some chrono date types.
