Superx++ is soon going to be integrated with XML Query (XQuery) version 1.0. This will afford relational type of querying capability to Superx++. You will be able to take any XML data or even Superx++ objects and query on them as if they are in an XML database. This approach is very powerful and will make Superx++ even more useful. Indeed, coupled with XQuery, Superx++ becomes a veritable database language. The XQuery constructs will provide the querying core, and the rest of the Superx++ language will provide the stored procedure constructs.
Details of the XQuery implementation for Superx++ will be released on the Emergent Logic web site (http://www.emergentlogic.com) and the Superx++ project web site (http://www.superxlang.org)
Keep your eyes peeled!
