The docs say I can't use non-const arrays at compile-time. But I want to, so
this is an enhancement request.

The following does not compile.

    int ctfeTest()
    {
        char[10] a; // <--- PROBLEM
        return 1;
    }

    const int A = ctfeTest();

This does

    int ctfeTest()
    {
        char[] a; // <--- OK
        return 1;
    }

but that's completely pointless. This doesn't:

    int ctfeTest()
    {
        char[] a = new char[10]; // <--- PROBLEM
        return 1;
    }

Nor does this:

    int ctfeTest()
    {
        char[] a;
        a.length = 10; // <--- PROBLEM
        return 1;
    }

Even if we can't have dynamic arrays, what's the harm with static ones?
