This should be

Is compiles now. Thanks!

I guess the "thread safe singleton" recipe is having difficulty. It
fails a boost assertion in method
    static T& instance()
trying to return *t

when ask for an instance of "z" in the test main.

Interesting finding. If I move the myARestistrar and myBRegistrar to be
inside main, then everything works.
But must auto-register.
