This is really nice, and useful, I would love to see more like this, but wonder if there isn't some room to join forces between the best JS libraries out there and try to create a common utility belt compilation (e.g. work to avoid conflicts, and namespace collisions, joint testing, shared convention and merge efforts on similar things) e.g. I would love to have the JavaScript equivalent of Apache commons / Guava (previously Google collections).

I mean, if there is one thing I do like about Java (when I can't use Scala for some reason), is those utility belt libraries (and JodaTime of course). Whenever I hit a wall trying to do something in plain old Java, Guava / Apache Commons seems to read my mind and have a data structure, or a utility to the rescue.

Do you think it's a good thing to strive for? Do you see it happening?
