Make that a Phobos bug. :)

The following is a reduced program that exhibits the problem. The 
presence or absence of the unused member function makes a difference:

import std.typecons;

struct S
{
    int x;

    // Bizarre: Comment-out this function to pass the assert in main.
    Tuple!(S) unused()
    {
        return tuple(S(7));
    }
}

void main()
{
    auto s = S(8);

    assert(tuple(s).expand[0] == S(8));
}
