I attempted this recently, but failed to figure out how to do the following:
QVector<int> triple = apply(QVector<int> {1,2,3},[](item) { return item*3;});
or
QVector<int> originals {1,2,3};
QVector<int> triples = originals.apply([](item) { return item*3;});
You do this:
std::vector<int> originals{1, 2, 3};
std::vector<int> triples = originals | ranges::view::transform([](int i) {
return i * 3; });
(modulo typos). Possibly even without the <int>, as std containers have CTAD.
