Hmm..., with boost (develop branch) + GCC 7.3 or Clang trunk, the following code runs fine:

std::vector<int> v1{1, 1, 1}; std::vector<int> v2{2, 2, 2};

for (auto&& tpl : boost::range::combine(v1, v2)) { auto [x, y] = tpl; // `auto&`, `auto const&` and `auto&&` also work fine x = 10; y = 20; }

for (auto&& [x, y] : boost::range::combine(v1, v2)) { x = 200; y = 200; }

FWIW, I just checked, and this works in the develop, but not master or 1.67. -- chris
