void main()
{
    static struct Iter
    {
        ~this()
        {
            ++_dtor;
        }

        bool opCmp(ref const Iter rhs) { return _pos == rhs._pos; }
        void opUnary(string op:"++")() { ++_pos; }
        size_t _pos;

        static size_t _dtor;
    }

    foreach(ref iter; Iter(0) .. Iter(10))
    {
        assert(Iter._dtor == 0);
    }
    assert(Iter._dtor == 2);
}

The iteration is done using destructed instances.

A foreach range statement:

foreach (iter; lower .. upper) {}

is always translated to a for statement:

for (auto iter = lower, limit = upper; iter != upper; ++iter) {}

So, this is a lifetime issue declared in for statement Initialize part.
