You have something slightly wrong with the above, vs. what I was suggesting.
You are placing your .bind(this) after the close paren of the .each() call.
What I said was simply place it after the end curly bracket of the function
itself... so like this:
Actually if you run
window.hello = "ninja";
var MyClass = Class.create ({
test: function()
{
this.items = $A([1]);
this.hello = "hello";
this.items.each(function(i)
{
alert(this.hello);
}.bind(this));
}
});
The above method of .bind(this)'ing an anonymous function is very common.

Exactly... I did say "IMHO", so you know, take it with a grain of salt as it
is my humble opinion. I am a proponent of prototype remaining as baseline as
possible and preach "wrap, wrap, wrap" on these lists all the time. And I
wasn't pissing, dude, just... you're in the prototype core list, and I'm
arguing against your bit, saying that .bind(this) should remain "the way" to
correct scope when needed, and you'd server yourself well (IMHO!!) to learn
to love it :)
