-    /// Parses any identifier including keywords.
-    ///
-    /// This is useful when parsing macro input which allows Rust keywords as
-    /// identifiers.
-    ///
-    /// # Example
-    ///
-    /// ```
-    /// use syn::{Error, Ident, Result, Token};
-    /// use syn::ext::IdentExt;
-    /// use syn::parse::ParseStream;
-    ///
-    /// mod kw {
-    ///     syn::custom_keyword!(name);
-    /// }
-    ///
-    /// // Parses input that looks like `name = NAME` where `NAME` can be
-    /// // any identifier.
-    /// //
-    /// // Examples:
-    /// //
-    /// //     name = anything
-    /// //     name = impl
-    /// fn parse_dsl(input: ParseStream) -> Result<Ident> {
-    ///     input.parse::<kw::name>()?;
-    ///     input.parse::<Token![=]>()?;
-    ///     let name = input.call(Ident::parse_any)?;
-    ///     Ok(name)
-    /// }
-    /// ```
-    fn parse_any(input: ParseStream) -> Result<Self>;
-
-    /// Peeks any identifier including keywords. Usage:
-    /// `input.peek(Ident::peek_any)`
-    ///
-    /// This is different from `input.peek(Ident)` which only returns true in
-    /// the case of an ident which is not a Rust keyword.
-    #[allow(non_upper_case_globals)]
-    const peek_any: private::PeekFn = private::PeekFn;
-
-    /// Strips the raw marker `r#`, if any, from the beginning of an ident.
-    ///
-    ///   - unraw(`x`) = `x`
-    ///   - unraw(`move`) = `move`
-    ///   - unraw(`r#move`) = `move`
-    ///
-    /// # Example
-    ///
-    /// In the case of interop with other languages like Python that have a
-    /// different set of keywords than Rust, we might come across macro input
-    /// that involves raw identifiers to refer to ordinary variables in the
-    /// other language with a name that happens to be a Rust keyword.
-    ///
-    /// The function below appends an identifier from the caller's input onto a
-    /// fixed prefix. Without using `unraw()`, this would tend to produce
-    /// invalid identifiers like `__pyo3_get_r#move`.
-    ///
-    /// ```
-    /// use proc_macro2::Span;
-    /// use syn::Ident;
-    /// use syn::ext::IdentExt;
-    ///
-    /// fn ident_for_getter(variable: &Ident) -> Ident {
-    ///     let getter = format!("__pyo3_get_{}", variable.unraw());
-    ///     Ident::new(&getter, Span::call_site())
