N.Becomes -- While tying a .Knot, the completion of one action sometimes leaves the .Cord in a position such that another action is partially completed. For example, when a .Wrap is completed then the .Tail_End might be in such a position that the first part of a .Collar has been performed. If a .Collar is the next step in the tying sequence after the .Wrap, then these steps can be written in the form of ".Wrap .Becomes .Collar."
