I've justed tested this and I think you're right (it seems a bit 
counter-intuitive though ;-) ).

How about this:

//file: foo.d
module foo;

struct Foo
{
    private int bar_;

    @property int bar() const
    {
        return bar_;
    }

    @property void bar(int b)
    {
        bar_ = b;
    }

    alias bar this;
}

//file:main.d
module main;

import foo;

void main()
{
    Foo b = Foo(10);
    int a = b;
    assert(a==10);

    a = 20;
    b = a;
    assert(b==20);

    assert(!__traits(compiles, b._bar));

}

//Compiled like so (to avoid linker errors):
$ dmd -lib foo.d -oflibfoo.a
$ dmd main.d -L-L. -L-lfoo
$ ./main
