I don't really see the point --- the patch won't provide any new
functionality in anything like its current form, because you can
always just write the separate expressions in the simple one to
one way.  If we do offer the row-on-the-left syntax then people
will try to put sub-selects on the right, and won't get anything
beyond an unhelpful "syntax error" message.  So my vote would be
to leave it alone until we have a more complete implementation.
