Yes, I agree, and that's a good thing.

What I meant was, someone who is new to this Turtle+SPARQL won't be greatly bothered by the extra characters that they *sometimes* have to use. It's a random little WTF, but every technology has its random little WTFs.

Right  the RDF world has a couple of random giant WTFs!

Well, change *always* has a cost. There's the obvious cost to the WG and to implementers, but there's also a cost for these new users who supposedly will benefit from the change. They will still be confronted with old data, old systems, old books, and old *people* (us!) who still use the old syntax.

And if it ain't broke, don't fix it. This is ugly but not broken.

Best,
Richard
