Should pass:

if (const int a = 4)  // Error: variable test.main.a cannot modify const
    assert (a==4);

More comprehensive code.
----
struct S
{
    int v;
    this(int n) { v = n; }
    const bool opCast(T:bool)() { return true; }
}
void main()
{
    if (int a = 1)
        assert(a == 1);
    else assert(0);

    if (const int a = 2)
        assert(a == 2);
    else assert(0);

    if (immutable int a = 3)
        assert(a == 3);
    else assert(0);

    if (auto s = S(10))
        assert(s.v == 10);
    else assert(0);

    if (auto s = const(S)(20))
        assert(s.v == 20);
    else assert(0);

    if (auto s = immutable(S)(30))
        assert(s.v == 30);
    else assert(0);
}

See:

which needs more work.
