Hopefully this (http://mootools.net/shell/gs4QG/) will help to explain
it. :)

This is not what I need, I need a way to access the properties of
object who called this function, while when defining the function also
access inside of it two other objects..
var myobj = new Object();
mypbj.val1 = 'useful param';
mypbj.useParam = function(val1/* but not really*/){
//somehow get the val1 inside this function
var _val1 = val1;
this.process(_val1);
} // here I can use .bind / .pass - but they are not work since they
will override the instance variables of the calling object
otherobj = new Object();
otherobj.process = function(val){
console.log(val);
}
otherobj.callback = myobj.useParam;
Can this be done in JS somehow?
Thanks!
