FAQ
  What is an Acme::CPANModules::* module?
    An Acme::CPANModules::* module, like this module, contains just a list
    of module names that share a common characteristics. It is a way to
    categorize modules and document CPAN. See Acme::CPANModules for more
    details.

  What are ways to use this Acme::CPANModules module?
    Aside from reading this Acme::CPANModules module's POD documentation,
    you can install all the listed modules (entries) using cpanm-cpanmodules
    script (from App::cpanm::cpanmodules distribution):

     % cpanm-cpanmodules -n CalculatingDayOfWeek

    Alternatively you can use the cpanmodules CLI (from App::cpanmodules
    distribution):

        % cpanmodules ls-entries CalculatingDayOfWeek | cpanm -n

    or Acme::CM::Get:

        % perl -MAcme::CM::Get=CalculatingDayOfWeek -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

    or directly:

        % perl -MAcme::CPANModules::CalculatingDayOfWeek -E'say $_->{module} for @{ $Acme::CPANModules::CalculatingDayOfWeek::LIST->{entries} }' | cpanm -n

    This Acme::CPANModules module contains benchmark instructions. You can
    run a benchmark for some/all the modules listed in this
    Acme::CPANModules module using the bencher CLI (from Bencher
