This is probably explained somewhere, but I've been unable to piece it
together in my own investigation. If I have a class:
class Foo {
has Int $!value;
}
I get the impression that the default constructor would allow me to
say
my Foo $foo .= new(value => 2);
Which seems to me to be a bit odd, since $!value is surely supposed to
be private. In any case, how would I write a custom constructor which
initialises $!value (and possibly many other fields which have to be
initialised based on some constructor parameters)? So far I think it's
something like this:
method new($class: Int $v)
{
my $self = $class.bless();
$self!value = $v;
return $self;
}
Or possibly
method new($class: Int $v)
{
$class.bless(value => $v);
}
Maybe both are valid. Rakudo didn't seem to understand private
attributes when I tried playing with this, so I have no real idea if
I'm barking in the correct forest.
