Good point.  Frankly, if you have a relevant large population of data
(>10,000 rows) to test, I'd love to see comparative execution tests
between the two query structures.

Fortunately, this will all soon become moot; Tom says that outer joins
have been stable in the 7.1 build for a while.  Speaking of which,
when's the 7.1 "release"?  Huh, huh?
