Well, in regards to simply choosing the right set of constructors, we 
appear to disagree on what's beneficial, so I guess I can't answer that.

In regards to the alternative design Eric presented, or my responses to 
it, it would buy this syntax:

    if (try_lock l = ...)
    {
    }

Not major, perhaps, but nice.
