I suspect the solution to my problem is something really trivial. I wrote a module called pitz that contains a class Issue:
>>> pitz.Issue.yaml_tag u'ditz.rubyforge.org,2008-03-06/issue' Then I try to load a document with that same tag, but I get a ConstructorError: ConstructorError: could not determine a constructor for the tag '!ditz.rubyforge.org,2008-03-06/issue' 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. Thanks!
