Since this doesn't exist, maybe one could use something like:

template<class T1, class T2 = void, class T3 = void, class T4 = void, class
T5 = void>
struct plus { ... };

// Specialisation for sequence

template<class T>
struct plus<T, void, void, void, void> { ... };

And the same for the lambda version (with the apply-member). This does use
partial specialisation, though.
