in reply to removing x from a list
Please search the monastery before asking your questions. Often, if it seems like others must have worked it out before, it's a FAQ. Super Search is your friend. Anyways, I think you'll find that your first question has been answered, as has your second.
Update: Oops! I misread your question as two. Ignore the first "answer," -- but, as stated above, splice is going to be handy.
