> Nicolas Dufour in an email thread titled "functions and list" started on November 2, 2005 requests the ability to create user defined aggregates.
> This functionality used to be in Cloudscape. It was disabled presumably because it was considered non-standard. However, most of the machinery needed for this feature is still in the code. We should re-enable user defined aggregates after we agree on acceptable syntax.
