Recurrences with Set Math

• Take some time off:

my $recur =
    DateTime::Event::Recurrence->weekly( days => [ 1 .. 5 ] );

my $days_off =
    DateTime::Set->from_datetimes
        ( dates => [ map { DateTime->new(%$_) }
                     { year => 2006, month => 7, day => 12 },
                     { year => 2006, month => 7, day => 13 } ] );

$recur = $recur->complement($days_off);
