If we're going to do this at all (which I'm still agin), I think the ROW
keyword is important to minimize ambiguity. If you are allowed to start
a statement with just "(x, ..." then there will be way too many
situations where the parser gets confused by slightly bad input,
resulting in way-off-base syntax error reports. Or worse, no syntax
error, but a function that does something else than you expected.
I know that ROW is optional in the bit of SQL syntax that this proposal
is based on, but that's only because the SQL spec says we have to, not
because it's a good idea.
