[windup-dev] Nested rules alternative?

Nested iterations create verbose rules with a lot of boilerplate. Maybe the iteration could be over tuples of vertices. Eg. in DiscoverJavaFilesCP, instead of forEach( windupConf ) ... ... ............ ..... forEach( javaFile ) we could query to get [ { windupConf, javaFile }, { windupConf, javaFile } ... ] And iterate over that. Anyone investigated this? IIRC from the Gremlin tutorial, this is possible. Ondra
