Private Attributes

Using exlamation mark as the twigil indicates tha the attribute is private. So has $!x will create a variable that can be accessed from within the class bug which won't have an accessor from the outside world.
use v6;

class Point {
    has $.x is rw;
    has $.y is rw;
    has $!weight;
    method reset {
        $.x = 0;
        $.y = 0;
        $!weight = 0;

my $a = => 23, y => 42, weight => 2);

say $a.x;  # 23
#say $a.weight;  # Exception: Could not locate a method 'weight' to invoke on class 'Point'


say $a.x;  # 0
