Named parameters

It is an error to pass the arguments as if they were positional.
For example, a call distance(30, 10) generates an error: ...

class Rectangle {
    has Int $.length = 1;
...
 
my $r1 = Rectangle.new(length => 2, width => 3);
say $r1.area();

has Bool $.done;

has Bool $!done;
method done() { return $!done }

use v6;

...
$point.set(joe => 100);
say $point;  # [100, 20]
