Matthew Stuckwisch gave two very interesting presentations at the 2023 Perl and Raku Conference in Toronto:

• Towards Slangs and DSLs (and GPLs)
• Brainfucking with RakuAST (/r/rakulang comments)

Highly recommended if you’re interested in using the new RakuAST capabilities in your code.

Bruce Gray also gave two, more basic presentations about Raku:

• Sorting *Whatever in $LANG
• Raku for Beginners
