// Annotations lets you mark points and ranges inside source code, for tests:
//
// Annotations Example(R"cpp(
// int complete() { x.pri^ } // ^ indicates a point
// void err() { [["hello" == 42]]; } // [[this is a range]]
// $definition^class Foo{}; // points can be named: "definition"
// $fail[[static_assert(false, "")]] // ranges can be named too: "fail"
// )cpp");
//
// StringRef Code = Example.code(); // annotations stripped.
// std::vector<Position> PP = Example.points(); // all unnamed points
// Position P = Example.point(); // there must be exactly one
// Range R = Example.range("fail"); // find named ranges
//
// Points/ranges are coordinates into `code()` which is stripped of annotations.
//
// Ranges may be nested (and points can be inside ranges), but there's no way
// to define general overlapping ranges.
