How do I create a module-local immutable class object?

[Andrej Mitrovic]

For crying out loud, shared fails too:

class Foo
{
    shared this()
    {
        value = true;
    }

    @property bool value() { return true; }
    @property void value(bool value) { }
}

void main()
{
    auto foo1 = new Foo;
    auto val1 = foo1.value;  // fail
}
