Since the data structures and interfaces, they are effectively
immutable.
Consider this:
final public class Cons extends ASeq implements Serializable {
private final Object _first;
private final ISeq _more;
public Cons(Object first, ISeq _more){
this._first = first;
this._more = _more;
}
}
Although Cons uses final fields and constructor fields, "_more" is an
ISeq; given that this could be mutable, so could cons.
