I think this is is a most important eventual use-case, and would like to 
see it better worked out - or else declared outside the scope of the 
proposed statement. As far as I can see, this does not cut it, since xml 
and html allow /sequencial repetition/ of tags and the results of the 
statement suites are passed as unordered namespaces/dicts.
