I know that it was discussed in person at times, and don't remember if 
it was discussed on list. Eric advocated a design that involved 
aggregates inline within a query. I don't know whether or not it was the 
same / similar to the commenter's suggested design.

When the working group did discuss aggregates, there was strong 
consensus on the SQL-like syntax and semantics.

If there are WG members who would like to re-consider this decision in 
light of the commenter's message, I'd like to ask that you volunteer to 
present the summary of the alternative design at a teleconference in the 
near future. If no one wishes to do this, I'd suggest that we conclude 
that there is consensus on the design as is, based on experience and 
familiarity with SQL aggregates.
