Dear Monks,

I am trying to understand the following code, in particular the set method::


use v6;

class Point {
    has $.x = 0;
    has $.y = 0;

    method gist { "[$.x, $.y]" }

    method set( :$x = $.x, :$y = $.y ) {
        $!x = $x; 
        $!y = $y;
    }
}

Can someone explain all of the syntax used in the set method?

And, another question if I may: is "Learning Perl 6" outdated?

Thanks.
