Using Mixin on objects

[xeoncross]

I'm doubt this is an issue, probably just a problem with what I'm doing but I can't get mixins to work using the default method.

MicroEvent.mixin    = function(destObject){
    var props   = ['bind', 'unbind', 'trigger'];
    for(var i = 0; i < props.length; i ++){
        destObject.prototype[props[i]]  = MicroEvent.prototype[props[i]];
    }
}

When trying with an object

var obj = {
    foo : 'bar',
     method : function() { }
};
    MicroEvent.mixin(obj);

I get can't convert undefined to object. If I change the method to this though it works:

MicroEvent.mixin2 = function(destObject)
{
    for (var k in MicroEvent.prototype)
    {
        if (MicroEvent.prototype.hasOwnProperty(k))
        {
            destObject[k] = MicroEvent.prototype[k];
        }
    }
}

Yeah, problem is, that you cannot set the event as prototype on the destObject, so just test if it is a function or not and handle it:

destObject = typeof destObject === "function" ? destObject.prototype : destObject;
