For fairness you should show Moo for the point example,

package Point {
  use Moose;
  has [qw/x y/] => ( isa => 'Int', is => 'rw' );

  sub inverted {
    my $self = shift;
    __PACKAGE__->new( x => $self->y, y => $self->x );
  }
}

Shy of that, this argument seems to mostly boil down into not core. This seems to be very much a reiteration of Stevan's thinking and work with Moxie. Good luck on it, it's just not very interesting to me. Out of all the problems I've had with Perl the inclusion of Moose in CORE, or a lightweight object system doesn't make the top-10. In my estimation the best thing Perl has going for it is Moose.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
