This could well be. However:

- I don't think this was an option a year ago when I started the array family
(weak excuse).

- The reference counting object is implemented in exactly 44 lines of code. I
am afraid a policy based approach could easily involve typedef expressions
twice the size (I know I am a bit vicious here).

Having said that, a little overhead could be more than justified if the boost
smart pointer is thread-safe, as I believe it is now. My shared_plain type does
not include any code to specifically support threaded applications (I am
counting on Python to get this right for me).
