class_docstr: Asserts that x is an element of the set S.
  
  Examples
  ========
  
  >>> from sympy import Symbol, Integer, S, Contains
  >>> Contains(Integer(2), S.Integers)
  True
  >>> Contains(Integer(-2), S.Naturals)
  False
  >>> i = Symbol('i', integer=True)
  >>> Contains(i, S.Naturals)
  Contains(i, Naturals)
