 * Mixes in one or more classes. Useful for inheritance and multiple inheritance.
 * @param A Function
 *  The constructor corresponding to the "class" we are mixing functionality into
 *  This function will get the following members set:
 *  __mixins: an array of [B, C, ...]
 *  constructors(subject, params): a method to call the constructor of all mixing classes, in order. Pass this to it.
 *  staticProperty(property): a method for getting a property name
 * @param B Function
 *  One or more constructors representing "classes" to mix functionality from

// Illustrative case
// YEAH -- ILLUSTRATIVE OF THE FACT THAT YOU CAN ISSUE PARALLEL QUERIES TO THE DATABASE INSTEAD OF SERIAL ONES LIKE A DUMB THREADED IMPLEMENTATION THAT IS INFERIOR FOR DOING WEB SERVERS

var results = {};
var count = 0;

for (var i = 0; i < recentBlogPostIds.length; i++) {

This is the most open letter ever. Other authors claim their letters are "open" because you can all read them, but in reality, they are nothing but the rants of one person, which you might not even completely agree with, or will piss you off.

By contrast, this letter is truly open and gives you the freedom to fork and modify it. Pissed about Mike Arrington investing? Want to give Richard Stallman some personal advice to stop publicly mentioning conspiracy theories he  may or may not believe in? The choice is yours. Simply fork this letter and post it on Hacker News and other places. Track its changes, and see what happens.
