With DateTime (as in your example) it looks like this:

  $ perl -MDateTime -lwe '
    $s = DateTime->new(year => 2005, month => 10, day => 1);
    $d = DateTime->new(year => 2005, month => 12, day => 1);
    print $d->delta_days($s)->delta_days'
  61

Yes, it does seem bizarre that you call ->delta_days twice, on different
types of object.
