Is there a range in Phobos for accessing all unordered
combinations of a range as:
foreach (const i, const a; r)
{
for (auto j = i + 1; j < r.length; ++j)
{
const b = r[j];
// Use a and b
}
}
excluding self-pairs, that is i != j

There is an open bug for that

Thanks.
So I construct a pairwise range with two implementation cases one
for RandomAccessRange and one for InputRange
