libclass-spiffy-perl 0.15-3 (s390x binary) in ubuntu bionic

 Class::Spiffy is a framework and methodology for doing object oriented
 programming in Perl. Class::Spiffy combines the best parts of Exporter.pm,
 base.pm, mixin.pm and SUPER.pm into one magic foundation class. It attempts to
 fix all the nits and warts of traditional Perl OO, in a clean, straightforward
 and (perhaps someday) standard way.
 .
 Class::Spiffy borrows ideas from other OO languages like Python, Ruby, Java
 and Perl 6. It also adds a few tricks of its own.
 .
 If you take a look on CPAN, there are a ton of OO related modules. When
 starting a new project, you need to pick the set of modules that makes most
 sense, and then you need to use those modules in each of your classes.
 Class::Spiffy, on the other hand, has everything you'll probably need in one
 module, and you only need to use it once in one of your classes. If you make
 Class::Spiffy the base class of the basest class in your project,
 Class::Spiffy will automatically pass all of its magic to all of your
 subclasses. You may eventually forget that you're even using it!
 .
 The most striking difference between Class::Spiffy and other Perl object
 oriented base classes, is that it has the ability to export things. If you
 create a subclass of Class::Spiffy, all the things that Class::Spiffy exports
 will automatically be exported by your subclass, in addition to any more
 things that you want to export. And if someone creates a subclass of your
 subclass, all of those things will be exported automatically, and so on. Think
 of it as "Inherited Exportation", and it uses the familiar Exporter.pm
 specification syntax.
