Bug: DT::Event::Recurrence Modifies Params

[Max Campos]

I noticed a little bug today.  DateTime::Event::Recurrence modifies the 
parameters that are passed to it.

Unfortunately I don't have the time to dig through the code and fix it 
myself.

Is there a defect tracking system that I should log this into?
btw - Dave, Flavio, etc, thanks for all of your hard work.  In the 
project I'm working on it has saved countless hours!

Example:
use DateTime::Event::Recurrence;
use Data::Dumper;
my @days = qw(1 2 3 4 5);
print Dumper([EMAIL PROTECTED]);
DateTime::Event::Recurrence->weekly(days => [EMAIL PROTECTED]);
print Dumper([EMAIL PROTECTED]);
$VAR1 = [
          '1',
          '2',
          '3',
          '4',
          '5'
        ];
$VAR1 = [
          0,
          1,
          2,
          3,
          4
        ];
