*Filter::Util::Call <https://metacpan.org/pod/Filter::Util::Call>* - Perl

corelist -a Filter::Util::Call  | grep -E 'released|5.(16|18|20)'

Filter::Util::Call was first released with perl v5.7.3
  v5.16.0    1.40
  v5.16.1    1.40
  v5.16.2    1.40
  v5.16.3    1.40
  v5.18.0    1.45
  v5.18.1    1.45
  v5.18.2    1.45
  v5.20.0    1.49


This is an unfortunately messy edge case that exposes the "cpan
distribution" <=> "perl module" disconnect we have to deal a lot with.

This is annoying, because anything that uses *other* than
filter::util::call *must* install the CPAN version.  But anything that uses
Filter::Util::Call on its own can do so from Perl itself.

Its also annoying because the "cpan distribution" that ships that module is
called "Filter" on CPAN, but "Filter-Util-Call" in perl/cpan/*

In the end what this means is that IF we need to depend on it, we need a 
virtual Filter-Util-Call ... which *can* also pull in dev-util/Filter.

Of course this might get painful if version numbers are randomized.
