dojo.clone: Error on cloning objects whose constructor require an object

[Anirban Mitra]

The example will make it clear

dojo.declare('ani', null, {
    constructor: function(param){
        this.c = param.attr;
    }
});

var nomind = new ani('anirban');
dojo.clone(nomind);

throws out error TypeError: Result of expression 'param' [undefined] is not an object.

Don't know if the bug can possibly be fixed but at least a more meaningful error can be thrown.

[Eugene Lazutkin]

It cannot be fixed. In general dojo.clone() works only on primitive types and naked objects. To clone proper objects made with dojo.clone() you should provide a cloning constructor, or (most probably) a special method, which does exactly that --- creates a clone of itself.

Since "it cannot be fixed" shouldn't you close this ticket as wontfix?
