Hi Larry,

Question 4: Return converters returning success/failure?

The option generally used elsewhere is: if we throw an exception, we return some special value; but the special value doesn't necessarily mean by itself that an exception was set. It's a reasonable solution because the caller only needs to call PyErr_Occurred() for one special value, rather than every time. See for example any call to PyFloat_AsDouble().

A bientôt,

Armin.
