signatures that are recorded for default methods

As with concrete methods on abstract classes, I would expect the 
specifications of the default methods to often contain text akin to 
"This default implementation does x, y, and z" since if the method is to 
be called by subtypes, the self-use patterns in the default method need 
to be known.
