Infinite lifetime is also only with `new`. The "extra work" with 
emplace and manual allocation is the domain of library code (e.g. 
`C c = alloc!C(ctorArgs);`).

The only issues with using library code instead of `new` are 
details like allocation of non-static nested classes and 
allocation of classes using private constructors etc.

It is true that classes rely on *uniqueness* to some extent, but 
uniqueness is not particular to GC memory.
