The Perl and Raku Conference 2023 in Toronto

Closures are helpful tools any language, but Raku’s more advanced subroutine handling make them quite a bit more useful than Perl5’s. This talk extends the basics of closures to include some of the more advanced features of Raku including things like using multimethods and introspection of anonymous subs to generate simpler, cleaner code that uses them.

One daunting issue for people approaching Raku is the sheer amount of syntax that it encompasses. This talk looks at ways to apply a bit of the syntax for subroutines and variables to generate simpler, more flexible, and maintainable code.
