I should have known.  This is straight down the rabbit hole, methinks,
and I think maybe we're overdoing the importance of the context graph in
a Versa query.

Just as I think Versa resource objects are names rather than actual
reified RDF resources, I think that other Versa types are values rather
than reified RDF literals.  I really do not think we want to play
Heidegger games with Versa.
