class_docstr: Kind for boolean objects.
  
  SymPy's ``S.true``, ``S.false``, and built-in ``True`` and ``False``
  have this kind. Boolean number ``1`` and ``0`` are not relevant.
  
  Examples
  ========
  
  >>> from sympy import S, Q
  >>> S.true.kind
  BooleanKind
  >>> Q.even(3).kind
  BooleanKind
