You mean C<< \d<4> >>, etc. I presume.

You didn't show us the iso_date rule.

In Perl5, I might write:
sub set_date {
my ($self, $date) = @_;
$date =~ /(\d{4})-(\d{2})-(\d{2})/ or croak "bad date format";
@$self{qw/year month day/} = ($1,$2,$3);
}
I could then call:
$foo->set_date('2002-09-04')
In Perl6 I can write:
sub set_date ( $date is rx/
