PyYAML: How to register my yaml.YAMLObject subclasses?

P: n/a
I suspect the solution to my problem is something really trivial.

I wrote a module called pitz that contains a class Issue:

Then I try to load a document with that same tag, but I get a

ConstructorError: could not determine a constructor for the tag

I think there's some namespace/scoping problem, because when I define
the same class in my interpreter and then run yaml.load(issue_file),
everything works OK.

So, how do I tell yaml to build pitz.Issue instances when it runs across
that tag?

Do I need to use add_constructor? If so, I'd *really* appreciate some
example usage.
