Multiple dispatch allows you to write many subroutines or methods with the same name, but taking a different number of or different types of parameters. In this talk I will look at multiple dispatch in Perl 6, including:
* How to write multi dispatch subs
* Arity based dispatch
* Basic type-based dispatch
* Candidate sorting - how the winner is chosen in a more complex type hierarchy
* Using subset types to do multiple dispatch on values
* Handling ambiguity: the 'is default' trait and using a proto as a fallback
* The .?, .+ and .* operators
All illustrated with example code, which runs today in Rakudo.
