Hi lots of work here! Wondering Did you consider evaluating if its worth
learning the quite involved rdf based syntaxes of many of these vs a simple
python jython or whatever script? Obviously you need Turing completeness so
I wonder (and a benchmark should bother to show imo) if its worth the
effort of ad hoc systems. (Let alone - and you can't really leave this
alone in 2012 - the lack of ide or tool support for non standard
programming paradigms)
