Boost.Range is not relevant here (other than the prvalue problem). `{...} | ...` is not allowed in C++. See https://bugs.llvm.org/show_bug.cgi?id=13069 In C++2a, you can use this for (auto rng = {...}; auto&& x : rng | ...) {...} thanks to http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0614r1.html.
