We could then have true libraries, and if we could version them all within the browser etc, we could share them between apps so we don’t duplicate painful downloads (not that we can’t add this to JS, but we could use rubygems).
Having true packages and namespaces, and a full environment like ruby in which we can share code in both worlds would be great. No need for Ruby to JSON etc. Send Ruby on down.
But in another dimension Marc A put Ruby into Netscape and we are all happy.
