That sounds indeed very useful. I'm just a user of SMW, but I think the best way to implement this would be as an extension similar to Semantic Result Formats, or even better, within that extension. It would then not be a separate parser function, but just an output format, that can be chosen via the 'format' parameter to an #ask query.
