Tobie, thanks for answer it is helpful but still what I am looking for
is practical advice how do you handle it in Prototype.
Just to clarify:
//this is what I would do without using Prototype
function PureClass(){};
var wow = new PureClass();
wow.constructor; // and I would get PureClass
// in Prototype the same
var PureClassPrototype = Class.create();
var wow_prototype = new PureClassPrototype();
wow_prototype.constructor; // here I get not very helpfull klass() -
ok it is helpfull and much better than nothing :)
wow_prototype.constructor == PureClassPrototype; // true
So I am maybe wrong but in JS I get what I want, but in Prototype my
guess is that there is some other way[i have few ideas how to go
around that but I am quite sure It is already solved]..
Or if I am going in very bad direction and what I am trying is
useless,stupid etc .. please let me know.. :)
Same is for e.g with Class.subclasses , I got Array of [ klass(), klass
() ] and than all I can do is '==' against Something, what I am
looking for is to have in that case array of [Something,
SomethingElse ]
Thanks
dzw!
