Fails to build: There is not a lot that can be done there as it is adequately captured by the CPAN testing.

Well, actually you could reduce the number of dependencies. This module doesn't need Perl6::Slurp at all, as it is easy to do without.

After that, and installing mod::

Now let me use that on a module I consider perfect:

$ perl -MTest::Copyright -MTest::More -wle'copyright_ok (); done_testi
+ng'
not ok 1 - found CPAN::Meta file
#   Failed test 'found CPAN::Meta file'
#   at /pro/lib/perl5/site_perl/5.12.2/Test/Copyright.pm line 91.
ok 2 # skip No CPAN::Meta object
1..2
# Looks like you failed 1 test of 2.
Exit 1

Well, of course, there is no META.yml during testing. That is generated in a make dist.

I'm not here to add only negative critiques. I'm very much into any means to increase the quality (kwalitee) of my modules, and I'm also very curious about how others think that can be achieved. So far I have however seen no additional value in this module in the form it is currently presented.

FWIW, I have created a meta-target in most of my Makefile.PL's that does all quality checks I can imagine. Of course that is only run after I have used Module::Release to check the module against all available and supported perl builds (I have over 70).
