That is an enum in a class, which is an entirely different beast. Class enums
are a C++11 addit

I am trying to expose a class with a boost::uuids::uuid member to Python. The
class is pretty simple:
class Article {

boost::uuids::uuid uuid;

which is exposed like this:
article
.def(init((arg("uuid")))
.def_readwrite("uuid", &Article::uuid);

a fairly simple converter registered to convert an iterable list of values

Normally you don't need to derive from Python's Exception object, and
indeed in my own custom exception implementations I never did so.
However, if this has changed, an FAQ entry is appropri

I have some glue code that calls a C++ function which can raise an
unsuitable_error exception. I have an exception translator which will
convert that to a more pythonic version (UnsuitableError), but when I
use that I get an "SystemError: 'finally' pops bad exception" error on
the python side.
