        // bindings. At this
        // point we look at any type mungers it was affected by previously (stored
        // in the weaver
        // state info attribute). Effectively we are working with a type munger and
        // yet may not have its
        // originating aspect in the world. This is a problem if, for example, the
        // aspect supplied
        // a 'body' for a method targetting an interface - since the top most
        // implementors should
        // be woven by the munger from the aspect. When this happens we store the
        // interface name here
        // in the map - if we later process a type that is the topMostImplementor of
        // a dangerous
        // interface then we put out an error message.
