Normalizing Const Syntax.

[Janice Caron]

I think it would be enormously wrong for

    const int x;

and

    const(int) x;

to mean two entirely different things (which I think was part of what
Scott was suggesting). But I do agree with all the rest of it.

So here's something to think about. Consider the following code:

    class C
    {
        const
        {
            T x;
            T f() { ... }
        }
    }

What would be the most intuitive meaning of f's const. Would it be:
(a) the function expects "this" to be const
(b) the function returns a const(T)
(c) both of the above simultaneously
(d) none of the above

I think (b).

In D2.012, the actual meaning is (a), but pretty much everyone agrees
that's not intuitive.
