In DMD64 v2.062, if you define a method with a default argument from a member
variable, DMD only complains if the method is actually called:

    class Foo
    {
        int a = 0;

        void bar(int x = a)
        {
        }
    }

    void main()
    {
        Foo f = new Foo();
        //f.bar();   -> does not complain with this commented out
    }

With the method call it produces the error "need 'this' to access member a",
which seems to be the defined behavior (but why not allow the default argument
to be variable? you can just read 'a' and push it on the stack).
