// Requires C++17. Tested on Clang 9.0.0, but should be portable.

// Modern C++ code uses ranges for more expressive code, compared to begin- and end-iterators. 
// When writing code that operators on ranges, you often end up with code like this (when not using concepts):
//
//   template <typename TRange>
//   auto foo(const TRange& range);
//
// So how do you call this with a fixed sequence of elements? You could pass an `std::vector`, 
// but that incurs one heap allocation (potentially two, if using an `std::initializer_list`).
