Presumably you mean to use that argument when calling map on the
emitter.  That works with 1.8.3, but since the YAML class included in
previous versions of ruby doesn't respond to the tagurize method it
won't work there.

So to be compatible I guess I'll just have to do something like:

yaml_type = to_yaml_type
yaml_type = YAML.tagurize(yaml_type[1..-1]) if YAML.respond_to? :tagurize
out.map(yaml_type)

That also won't work properly with older versions.

Yeah, I don't really care about that.  I really only noticed it when
comparing the ouput to older versions because of the other issue.
