CPAN-river-1000: failures as of perl-5.27.8

You may find data from a test run of the "CPAN-river-top-1000" against 
perl-5.27.8 here:

http://thenceforward.net/perl/misc/cpan-river-1000-perl-5.27-master.psv.gz

The file above presents the data in the same format which I used for 
5.27.6 and 5.27.7 in November and December.  What is essentially the 
same data is presented in a slightly different format here:

http://thenceforward.net/perl/misc/xformat-cpan-river-1000-perl-5.27-master.psv.gz

Reviewing the data from 5.27.0 through 5.27.8, I came to realize that 
certain CPAN distributions could fail to be reported on under certain 
conditions.  See attachment 'moosex-getopt.psv', which extracts data for 
MooseX-Getopt from the first link above.  Note that this distribution 
lacks data for the most recent release, 5.27.8.  Why is that?

Hold that question for a moment.  Let's look at the second attachment, 
'xformat-moosex-getopt.psv'.  Here, rather than have the last four 
columns empty strings, we instead print a lower-case 'x' to those fields 
to improve readability.

The reason why MooseX-Getopt lacks data for the most recent release is 
that one of its prerequisites, Getopt-Long-Descriptive, began to 
experience test failures against blead in the 5.27.7-to-5.27.8 
development cycle.  Once it failed to install, none of its reverse 
dependencies, including MooseX-Getopt could be attempted by 'cpanm', the 
installer used in gathering this data, or by App::cpanminus::reporter, 
the test reporting library in use.

The third and fourth attachments, 'getopt-long-descriptive.psv' and 
'xformat-getopt-long-descriptive.psv', add data for that distribution.

The fifth attachment, 'changes-5.27.7-to-5.27.8.csv', presents another 
subset of the data set found at the second link above.  It presents 
results from just the last two monthly releases for those distributions 
which either (a) had a change of grade between 5.27.7 and 5.27.8; or (b) 
received a grade other than 'PASS' in 5.27.8.

Anyone who wishes to follow up on this data or help me
further develop analyses like this should contact me.

Thank you very much.
