This will translate try and the C++ error into an appropriate Python exception.
(currently an IndexError on std::out_of_range and a RuntimeError otherwise
The translation is performed according to the following table
(preserving the what() message). ::
(the ``std::`` prefix is omitted from the C++ identifiers):
+-----------------------+---------------------+
| C++ | Python |
+=======================+=====================+
| ``bad_alloc`` | ``MemoryError`` |
+-----------------------+---------------------+
| ``bad_cast`` | ``TypeError`` |
+-----------------------+---------------------+
| ``domain_error`` | ``ValueError`` |
+-----------------------+---------------------+
| ``invalid_argument`` | ``ValueError`` |
+-----------------------+---------------------+
| ``ios_base::failure`` | ``IOError`` |

The ``what()`` message, if any, is preserved. Note that a C++
``ios_base_failure`` can denote EOF, but does not carry enough information
for Cython to discern that, so watch out with exception masks on IO streams. ::
