> Objects, list and maps variables are only reference to them. Meaning you can't assign a new list to a constant variable but you can modify the list itself.

In what contexts is this useful? I know it matches some other languages view of `constant`, but I feel that this sort of behaviour is very surprising to a user.

Assuming the following code:

    object Person {
        str name = "Joe", | Fields can have default values
        int age = 35,
    }
    const me = Person{...}
    const [int] list = [4, 5, 6]

In what contexts is it useful to allow the name of `me` to be changed, or the length of the list to be changed, while disallowing the variable to reference a different underlying object?

Wouldn't the expectation of a programmer be the other way around? IOW, a symbol that is declared as constant can be a reference to any constant object, so the programmer can always assign that symbol to another constant object, but the objects themselves should not be mutable.
