public final class AddOnceByIdentity<T>
extends Object

THE add-if-not-already-there by IDENTITY: item is added to list unless that very object is already in it. For symbols, scopes and parse nodes, whose equals is not identity (two same-named symbols in different scopes may compare equal), when the order they were met in matters (a Set from an IdentityHashMap has no stable order). Use this; never a private noneMatch(existing -> existing == x).
