+ * variable can't be deleted.
+ * VAR_ARRAY_ELEMENT - 1 means that this variable is an array
+ * element, so it is not legal for it to be
+ * an array itself (the VAR_ARRAY flag had
+ * better not be set).
+ * VAR_NAMESPACE_VAR - 1 means that this variable was declared
+ * as a namespace variable. This flag ensures
+ * it persists until its namespace is
+ * destroyed or until the variable is unset;
+ * it will persist even if it has not been
+ * initialized and is marked undefined.
