sorted: can modify elements - why normal?

In both cases its not using the initializer list constructor so you have
ns = {9,9,9} and vc = {-1,-1,-1}. The loop sets each element in ns to -1.

Hi. I don't understand the code in the test/test_sorted.cpp:

std::vector ns(3, 9);
for (auto&& n : sorted(ns)) {
n = -1;
}
Vec vc(3, -1);
REQUIRE(ns == vc);

Why so? Doesn't vc must be (-1, -1)? Can you explain?
