OK... although I'd rather have constructors than aggregate initialisation 
syntax. If the problem is performance, surely the compiler can optimise 
away the difference (given that it's a standard library component with 
known semantics)?

Anyway, it sounds like this battle is already lost.

Is there a rational for not allowing zero-sized arrays? What is the 
intended semantics of:

    array<int> a;  // Or array<int,0>.
    assert( a.empty() );

? Isn't this kind of thing likely to occur in generic template code?
