What are use-cases? C++ has references as a sugar for "dereferenced pointer", but other languages leaved this approach because of confusions (mostly with memory operations). Don't think we need them much.
Though, you still may to update your var passing base object (and in Rhino even for local vars of function having access to the activation object). Dmitry.
