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.
