If you just need to concatenate two sequences, you can use fold_backward
and
push_front, something like:
template
struct concatenate : mpl::fold_backward<
    V1,
    V2,
    mpl::push_front<_,_> // please verify this -- not sure about the
order -- may be <_2, _1>
...
{};
After taking a look at the joint_view documentation:
...
Complexity
Amortized constant time.
... I actually regret that I ever suggested using fold_backward/push_front
for this purpose :)
