[Xotcl] Expand init arguments and custom destructor

From: Krzysztof Frukacz <>

Thank for all your help so far. I have two more questions:

1. Is it less efficient if I expand a list before providing it as an
argument for init?

set myList [list 1 2 3 4]

MyClass myObject $myList


eval MyClass myObject $myList

2. When do I need to create a custom destructor? I create objects inside
init - do I have to do that in this case, or will those object be
destroyed automatically when I destroy their parent?

MyClass instproc init args {

        my contains {
                MySecondClass innerObject

Best Regards,
