 /** Property address.
  *
- * When accessing part of a property that is non-scalar and mutable,
- * a read-modify-write (or get-modify-set) operation is necessary.
- * To accomodate this, the address item must hold a temporary copy of the
- * property value.
+ * When an access or index operation is performed on a property, the getter
+ * is run and the prefetched value is stored in @c tvalue. If the property
+ * is a non-scalar value type (a struct), then we might want to point to
+ * the proper @c var node inside it. @c tpos is used for this purpose.
+ *
+ * The assignment operator will modify @c tvalue and at the end the setter
+ * is called to store @c tvalue back into the property.
