We would like a tupleList.Select((a, b) => a + b) method on every n-tuple which takes n arguments. This makes writing functional mappings a lot nicer when working with tuples, since lambda parameter lists do not support destructuring (yet?).
tupleList.Select((a, b) => a + b)
static IEnumerable<TRes> Select<TSource1, TSource2, TRes>(this IEnumerable<(TSource1, TSource2)> source, Func<TSource1, TSource2, TRes> fn) => source.Select(t => fn(t.Item1, t.Item2));
Analogue implementations for tuples of size 3, since we would consider any larger tuples to be better represented by a custom struct.
