# For a line that has two values, which may be missing but will always be in the order of Integer,String
class Line {
  my @default-values = [ 42, Str ]; # purely theoretical
  
  has @.values;
  
  method new($line) {
    my @values = $line.split(',');
    for ^2 -> $idx {
      @values[$idx] ||= @default-values[$idx];
    }
    self.bless(:@values);
  }
}

my $parsed-line = Line.new(',"life"');
dd $parsed-line.values;

my $second = Line.new('555,""');
dd $second.values;

my $third = Line.new(',');
dd $third.values;
