In AS2 you can do:
Function.prototype.bind = function(object) {
var __method = this;
return function() {
__method.apply(object, arguments);
}
}
//////
class x {
function setFocusHandler() {
var func = function() {
trace("this="+this) // scope is class x
}
label.onKillFocus = func.bind(this);
}
}
////
But this is just a variation on the Delagate.create(this, func) pattern
