I propose that the `Set` ABC API should be augmented to contain all of the

the duck typing capabilities of the `Set` abc.
Two thoughts. First, I believe Guido intentionally omitted the named set
methods from the ABC — perhaps the reasons are documented in the ABC PEP.
Second, most APIs are easily expanded by adding new methods, but ABCs define a
minimum for other classes to implement. So if we added new methods, it would
likely break code that was only meeting the existing minimum.
Concur with Raymond.
Also I want to add that ducktyping does not relay on ABCs. Actually they
are opposite approaches.
