I've tried to be quiet but I couldn't let this dig slide by ... 

Jena, which Jeremy's software is based on, *does* allow literals as
subjects internally (the Graph SPI) and the rule reasoners *do* work
with generalized triples just as most such RDF reasoners do. However, we
go to some lengths to stop the generalized triples escaping. So the lack
of subjects as triples in the exchange syntax or the publicly
standardized model has had no detrimental impact on our ability to work
with them internally.
