I've found my "wish item"...  I wish that queries could expand ranges in
much the same fashion that BETWEEN expands into two query nodes.

That way, you can use a range to pick data from a large table, and not
revert to a Seq Scan+Filter, which is what I'm seeing for the following
sort of query:
  select * from some_data where '[2010-01-01,2010-02-01)'::daterange @> whensit;
-- 
let name="cbbrowne" and tld="gmail.com" in String.concat "@" [name;tld];;
