1/// Opens a scope. Two variants:
2/// - profiling::scope!(name: &str) - Opens a scope with the given name
3/// - profiling::scope!(name: &str, data: &str) - Opens a scope with the given name and an extra
4/// datafield. Details of this depend on the API, but it should be a &str. If the extra data is
5/// named, it will be named "tag". Some APIs support adding more data (for example, `optic::tag!`)

7/// ```
8/// profiling::scope!("outer");
9/// for _ in 0..10 {
10/// profiling::scope!("inner", format!("iteration {}").as_str());

40/// - register_thread!(name: &str) - Registers the thread using the given name
