Set having the capability to assign an object of the same type was inconsistently implemented. Some places it was not implemented at all, some places it was a shallow copy, some places a deep copy. Given that it doesn't seem likely to ever be used, and if it is needed it is easy enough to do outside of the library this code has been removed.
