It would make named function parameters *very* easy to do. :)
SELECT *
FROM foo_func( a => 2, b => 5, c => current_timestamp::timestamp with time zone
);
would be equivalent to
SELECT *
FROM foo_func( c => current_timestamp::timestamp with time zone, a => 2, b => 5
);
and both would Do The Right Thing. It also opens the door to default
parameters for those who want them.
