Safe reference counting cannot be implemented as a library

[PuglyWUgly via Digitalmars-d]

  Why care about this?

  Even Rust doesn't try to solve this problem...because it isn't 
really a problem in practice.

  In c++/rust code you use value/unique types 99.9% of the time, 
and reference counting is only for shared/aliased objects.


  Reference counting == rare and unimportant
