llocating objects on a predetermined memory address has become a popular idiom in recent years, particularly in mobile programming, embedded systems, and custom garbage collectors. However, the technique shown in
any design patterns and programming idioms rely on the use of friend declarations. However, when friend declarations are used in templates, the obfuscated syntax can bewilder even expert programmers. This
