I'm obviously opinionated on this point (backbone/underscore user), it just seems like it comes with so much i wont ever user - and could easily add via a mixin on a per project basis (in a nice functional manor). I also can't get over extending the native prototypes. Dealing with too many moving parts in modern web apps to go and start extending things that weren't built that way - maybe in the ruby world it just feels better to have it on the prototype directly. I suppose im getting off topic tho.

This lib (joosy) was built to satisfy your particular set of needs, and it seems that it does so well. Cheers to that.
