[windup-dev] Iteration using Java's for?

Hi, is there a reason against querying the graph, storing it to Java variable, iterating it using for( Foo foo : foos ), and skipping the varstack and when() etc? Basically, the current rules structure is appropriate for e.g. XML based rules whose XSD would translate to this structure, but if we provide Java and Groovy, the above way would be shorter to write, and users might tend to do that. Thanks, Ondra
