Sure, here is it:

=========
Here are some AOP features I plan to add by the weekend:
1. A trait can import/implement other traits. Scala supports that.
It's gonna look like this:
var trait1 = defineClass.trat({
m: function () { ... }
});
var trait2 = defineClass.trait({
_super: trait1 //
m2: function () { ... }
});
Here trait2 includes trait1 implementation. It can override existing
methods and call them as this._super(..).
trait1, trait2 themselves are functions that receive a class/prototype
and return a class/prototype with the trait applied.
2. Python-like class/function decorators. Apply behavior after class
is composed:
// define a decorator. This one will log exceptions
var logException = defineClass.decorator(function () {
try {
// call the method that is being decorated
return this._super();
}
catch (err) {
console.log(err);
throw;
}
});
// apply the decorator to a method
var Bar = defineClass({
// let me reserve the $ for this
$baz: logException,
baz: function (x) {
return 1/x;
}
});
// apply the decorator to all methods:
var Foo = defineClass({
$: logException,
m: function (x) {
return 1/x;
}
});
A chain decorators can be applied to a class/method.
In fact, the logException is just a function that receives and returns
a class/method/prototype. defineClass just applies it uses the return
value.
As I wrote above, trait1 is a function too, so it can be used as decorator too.
