I wouldn't be averse to hiding the implementation here.  The main reason
it's not already is because the queryparser class was pulled out of
omega and never really cleaned up fully.

The major obstacle is that you end limiting what can be done or exposing
all the container methods via the class API.  For example, just a get
and set pair don't allow you to delete a prefix, delete all prefixes
(i.e. self->prefixes.clear()), iterate through all prefixes, ...

Not all operations are that useful though.  We could look at how omega
uses these members and start from there.
