I can't speak for Françios but here's one use case: I used similar things in https://code.google.com/p/prebake/wiki/YSON The design principle was that we can get the benefits of both declarative configuration and dynamic scripting languages by running scripts that produce serializable & relocatable data bundles that include pure functions. That wiki page is part of a build system that tries to get the benefit of static declarative build systems and the flexibility of build shell scripts by using a hacked version of Rhino that allows serialization of some closures and exposes the inferred dependency graph via a web service for inspection by other tools. _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
