nicer syntax
avoid use of Path::Class API
maximal use of Path::Tiny over Path::Class
use my new [Test::CleanNamespaces] plugin!
"dzil test" will run tests without extra testing variables, for "dzil release" or "dzil test --release"

This is the intention of my aborted plugin [TestInstall] (2013-09): to weed
out test issues that only manifest when AUTHOR_TESTING or RELEASE_TESTING are
*not* set (e.g. bad test count, conditional module loading).

          - switch to renamed form of now-deprecated plugin
            [MungeData::WithDataSection]
          - "dzil test" will run tests without extra testing variables, for
            "dzil release" or "dzil test --release" -- this will weed out test
            issues that only manifest when AUTHOR_TESTING or RELEASE_TESTING
            are *not* set (e.g. bad test count, conditional module loading).
