Yeah, and funny enough, it's still "to be" included in the next version 
of MySQL ... and what they have so far for 4.1 (in the 4.1.1 Alpha) is 
one implementation of subselects for the FROM clause and apparently 
another one for the WHERE clase (this is an assumption based on the fact 
that subselects support different language features if they are in the 
FROM clause or the WHERE clause). Fortunately I don't have to maintain 
any of that code.
