Ok, it's the year of the Ox, but you get the idea. Regardless, it's shaping up to be a very interesting one for MooTools. There are many things going on with the framework and we thought we'd give you a heads up on what you should expect in the coming weeks and months.
During the last couple of days, there has been a discussion in various places about JavaScript frameworks implementing Sizzle, the new CSS selector engine by John Resig, which is allegedly the fastest.
Resig wrote Tom an email, saying that he would be pleased if MooTools joined the other frameworks by implementing Sizzle in its codebase, replacing our own selectors engine. I don't really know how many frameworks are actually thinking of using Sizzle in place of their own selectors code, as the only source I can find for this is Ajaxian.
Their information about Dojo wasn't correct, so I'm assuming that information about other frameworks is incorrect as well. I do know that Dojo is considering including Sizzle as part of the Dojo foundation, based on an email Dylan Schiemann wrote to Aaron Newton. As I understand it, Sizzle would become a Dojo Foundation project, with the ultimate goal of including it into Dojo Toolkit. They have this idea of having the major framework developers all contribute to a unified CSS selector engine.
Now that you know the general picture, let me explain why this is a bad idea not only for MooTools, but for any framework other than Dojo and jQuery.
