Raku
Raku is a high-level programming language suitable for application-building and scripting. It has an extremely versatile syntax and supports procedural, object-oriented, as well as functional programming. Chiefly designed by Larry Wall (and originally named Perl 6), it is a member of the Perl family of programming languages. The preferred implementation is Rakudo. The best documentation is available at docs.raku.org.
Installation
There are three main options to install Rakudo, which is the most mature and production-ready implementation of Raku: installing the package that's provided for zypper; downloading the latest pre-compiled release from upstream; or compiling the source code yourself. All options come with zef, the preferred module manager for Rakudo. For detailed instructions on each option, it's best to refer to the upstream documentation.
There is also the Rakudo Star Bundle, which ships Rakudo and zef together with a selection of modules. The Star Bundle generally needs to be installed from source, following the instructions linked to on that webpage. For the Star Bundle only, there is also a Docker image.
