Interesting set of Raku features to focus on...

The most important Raku features are Command Line Interface (CLI) and grammars.

CLI support is a _usual_ feature -- see "docopt" implementations (and adoption), for example. But CLI is built-in in Raku and nice to use.

As for the grammars -- it is _unusual_ a programming language to have grammars as "first class citizens" and to give the ability to create (compose) grammars using Object-Oriented Programming.
