I think so; I'll have to look at what is returned from type() in some  
more detail.

It appears that the two main culprits for passing strings off to  
Ontology::Term are the Bio::OntologyIO::obo and  
Bio::OntologyIO::dagflat parsers.  I can add some code in there to  
change those to DBLinks prior to creating Ontology::Term instances,  
which should clean that up.
