View sequence.h
| // 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`). |

| // Does not work on MSVC, since they use a different preprocessor algorithm than clang and gcc. | |

| // foreach(const &, myFoo1, myFoo2, myFoo3, _.foo()); | |
| // foreach(&&, a, b, c, sum += _); | |
