-/// Invalidate any `proc_macro2::Span` that exist on the current thread.
-///
-/// The implementation of `Span` uses thread-local data structures and this
-/// function clears them. Calling any method on a `Span` on the current thread
-/// created prior to the invalidation will return incorrect values or crash.
-///
-/// This function is useful for programs that process more than 2<sup>32</sup>
-/// bytes of Rust source code on the same thread. Just like rustc, proc-macro2
-/// uses 32-bit source locations, and these wrap around when the total source
-/// code processed by the same thread exceeds 2<sup>32</sup> bytes (4
-/// gigabytes). After a wraparound, `Span` methods such as `source_text()` can
-/// return wrong data.
-///
-/// # Example
-///
-/// As of late 2023, there is 200 GB of Rust code published on crates.io.
-/// Looking at just the newest version of every crate, it is 16 GB of code. So a
-/// workload that involves parsing it all would overflow a 32-bit source
-/// location unless spans are being invalidated.
-///
-/// ```
-/// use flate2::read::GzDecoder;
-/// use std::ffi::OsStr;
-/// use std::io::{BufReader, Read};
-/// use std::str::FromStr;
-/// use tar::Archive;
-///
-/// rayon::scope(|s| {
-///     for krate in every_version_of_every_crate() {
-///         s.spawn(move |_| {
-///             proc_macro2::extra::invalidate_current_thread_spans();
-///
-///             let reader = BufReader::new(krate);
-///             let tar = GzDecoder::new(reader);
-///             let mut archive = Archive::new(tar);
-///             for entry in archive.entries().unwrap() {
-///                 let mut entry = entry.unwrap();
-///                 let path = entry.path().unwrap();
-///                 if path.extension() != Some(OsStr::new("rs")) {
-///                     continue;
-///                 }
-///                 let mut content = String::new();
-///                 entry.read_to_string(&mut content).unwrap();
-///                 match proc_macro2::TokenStream::from_str(&content) {
-///                     Ok(tokens) => {/* ... */},
-///                     Err(_) => continue,
-///                 }
