template<class L, class S> using mp_intersperse = /*...*/;
Inserts the separator `S` between the elements of `L`.
Inserts the separator `S` between the elements of the list `L`.
`mp_intersperse<L<>, S>` is `L<>`. `mp_intersperse<L<T1>, S>` is `L<T1>`.
`mp_intersperse<L<T1, T2, T3, ..., Tn-1, Tn>, S>` is `L<T1, S, T2, S, T3, S, ..., Tn-1, S, Tn>`.
## mp_split<L, S>
template<class L, class S> using mp_split = /*...*/;
Splits the list `L` into segments at each separator `S` and returns a list of
the segments.
`mp_split<L<>, S>` is `L<L<>>`. `mp_split<L<T...>, S>`, where `S` does not occur in `T...`,
is `L<L<T...>>`. `mp_split<L<T1..., S, T2..., S, T3...>, S>` is `L<L<T1...>, L<T2...>, L<T3...>>`.
The segments may be empty; `mp_split<L<S, X, Y, S, S>, S>` is `L<L<>, L<X, Y>, L<>, L<>>`.
