The examples are all undeniably verbose, but the source shows that many short options are also supported, specifically to copy those you would expect if migrating from the alternatives: https://github.com/lizmat/App-Rak/blob/main/lib/App/Rak.raku...

So

    rak -C2 foo

will do what you expect.

[Edited to add] Also, the `\b...\b` form is shorter with rak - as the README also states where it documents this pattern form:

> §string

> If the pattern starts with §, then it indicates that the string should occur as a word (with word-boundaris on both ends) in the item. Basically a shortcut to specifying string --type=words. Any --smartcase, --smartmark, --ignorecase or --ignoremark arguments will be honoured.
