The note by merlyn is simple and best . I posted my previous message not seeing merlyn's reply and yours too . You can ignore it , just that the extended pattern match with assertions was not included in the pattern and that is what I had to mention
Such a comment best goes into an update to your original node. Simply put <strong>Update</strong> and your update at the end of your orignial node. You know that you can change/update most of your nodes (apart from root nodes in some sections), don't you?
