*py::builtins::BaseException::*\ BaseException
==============================================

.. code-block:: cpp

     BaseException();                                        // 1

     explicit BaseException(const char* what);               // 2

     BaseException(const std::string& what);                 // 3

     template <class... args>
     BaseException(const args&... what)                      // 4

     BaseException(const BaseException& other);              // 5

     BaseException(BaseException&& other);                   // 6

1.   Constructs a BaseException with empty explanatory message.

2.   Constructs a BaseException with given explanatory message.

3.   Same as 2.

4.   Constructs a BaseException with given explanatory values.

5.   Constructs a BaseException from another BaseException.

6.   Same as 5.

.. note::

     (1), (2) and (3) are deprecated and will be removed when
     ``py::builtins::any_t`` is implemented. But changes should
     not break old codes, as after removal (4) will be candidate
     for all calls to them.

-------------------

``args``: The types of explanatory values.


Parameters
----------

``what``: (1), (2) and (3): explanatory string, (4): explanatory
