For years now, I've been using something like this as my default constructor:

sub new {
    my $class = shift;
    my %params = @_;

    my $self = {};
    foreach (qw(param1 param2 param3)) {
        $self->{$_} = $params{$_}
    }

    # further initialization.
    #  ...

    bless $self, $class;
}

Now I'm transitioning to using fields, as I quite like the idea and it's been in core since 5.6.1. The documentation for fields suggests something like this:

use fields qw(param1 param2 param3);

sub new {
    my ClassName $self = shift;
    unless (ref $self) {
        $self = fields::new($self);
    }

    # initialization
    # ...

    return $self;
}

So, my questions are: Is bless $self, $class being phased out in favour of the my HardCodedClassName $self form? Are there any benefits to this? Will inheritance still work even despite the hard coded class name?

Update: Sorry, I saw that for subclasses, fields still recommends the my $class = shift form. So I don't need to bless $self, class anymore, since fields does that for me, but I don't have to specify the class name in the code.
