+/*
+ * Note that the numeric methods are not supported.  This is primarily
+ * because of the way coercion-less operations are performed with
+ * new-style numbers; since we can't tell which side of the operation
+ * is 'self', we can't ensure we'd unwrap the right thing to perform
+ * the actual operation.  We also can't afford to just unwrap both
+ * sides the way weakrefs do, since we don't know what semantics will
+ * be associated with the wrapper itself.
