| Subject: | Bundles extraneous modules in inc/ |
Building Class::Trigger on perl 5.20.0 or newere gives a lot of "Possible precedence issue with control flow operator" warnings from the bundled old version of Test::Builder, pulled in by either the 'use_test_base' directive. It turns out neither Test::Base nor IO::WrapTie is actually used, and the Test::More version requirement is satisfied by core since well before the 5.8.1 requirement Module::Install imposes.
If the goal is to have no non-core requirements, IO::Scalar could be eliminated by using open to a reference instead, which is supported since 5.8.0.
Applying the following patch and rebuilding the dist gets rid of the spurious includes:
$ git diff --cached Makefile.PL
diff --git a/Makefile.PL b/Makefile.PL
