obj_unset:(key) -- return self
* operator
<< : obj_set = Set() << key1 << key2 << key3 -- set
>> : obj_set = Set() >> key1 >> key2 ; -- unset
& : obj_set1 & obj_set2 --> return obj_set3
| : obj_set1 | obj_set2 --> return obj_set3
== : obj_set1 == obj_set2 --> return bool
a=Set{'a','b'}
b=Set{'a','b','c'}
c = a ~ b -- {'c'}
d= b ~ a -- {'c'}
a==b ---> 等同 c = a ~ b ; c:empty()
