This programming language may be used to instruct a computer to perform a task.
If you know Perl5i, please write code for some of the tasks not implemented in Perl5i.
While the Perl examples on Rosetta Code are correct, some of them reflect an older style of using the language. After all, Perl has been around since the 80s; Perl5 was released in 1994. Things that were barely manageable on a 386 running at 16 MHz with 4MB of RAM are a breeze, now.
Object-Oriented Perl has been transformed by the development of Moose and its lightweight cousins, Mouse, Moo, etc.
A number of modules encourage good non-OO style and simplify the boilerplate involved, such as Modern::Perl. I've decided to treat one of those modules, perl5i, as if it were a language on its own. While the existing code focuses on the use of Perl as a quick and easy scripting language, I want to emphasize its use for more engineered situations. Were I use OO, I've gone for a minimal style. As well, I've avoided POD and used minimal per-routine documentation.
