+/// - [`ParseStream::peek2`][crate::parse::ParseBuffer::peek2]
+/// - [`ParseStream::peek3`][crate::parse::ParseBuffer::peek3]
+/// - [`Lookahead1::peek`]
+///
+/// The peek will return `true` if there are no remaining tokens after that
+/// point in the parse stream.
+///
+/// # Example
+///
+/// Suppose we are parsing attributes containing core::fmt inspired formatting
+/// arguments:
+///
+/// - `#[fmt("simple example")]`
+/// - `#[fmt("interpolation e{}ample", self.x)]`
+/// - `#[fmt("interpolation e{x}ample")]`
+///
+/// and we want to recognize the cases where no interpolation occurs so that
+/// more efficient code can be generated.
+///
+/// The following implementation uses `input.peek(Token![,]) &&
+/// input.peek2(End)` to recognize the case of a trailing comma without
+/// consuming the comma from the parse stream, because if it isn't a trailing
+/// comma, that same comma needs to be parsed as part of `args`.
+///
+/// ```
+/// use proc_macro2::TokenStream;
+/// use quote::quote;
+/// use syn::parse::{End, Parse, ParseStream, Result};
+/// use syn::{parse_quote, Attribute, LitStr, Token};
+///
+/// struct FormatArgs {
+///     template: LitStr,  // "...{}..."
+///     args: TokenStream, // , self.x
+/// }
+///
+/// impl Parse for FormatArgs {
+///     fn parse(input: ParseStream) -> Result<Self> {
+///         let template: LitStr = input.parse()?;
+///
+///         let args = if input.is_empty()
+///             || input.peek(Token![,]) && input.peek2(End)
+///         {
+///             input.parse::<Option<Token![,]>>()?;
+///             TokenStream::new()
+///         } else {
+///             input.parse()?
+///         };
+///
+///         Ok(FormatArgs {
+///             template,
+///             args,
+///         })
+///     }
+/// }
+///
+/// fn main() -> Result<()> {
+///     let attrs: Vec<Attribute> = parse_quote! {
+///         #[fmt("simple example")]
+///         #[fmt("interpolation e{}ample", self.x)]
+///         #[fmt("interpolation e{x}ample")]
+///     };
+///
+///     for attr in &attrs {
+///         let FormatArgs { template, args } = attr.parse_args()?;
+///         let requires_fmt_machinery =
+///             !args.is_empty() || template.value().contains(['{', '}']);
+///         let out = if requires_fmt_machinery {
+///             quote! {
+///                 ::core::write!(__formatter, #template #args)
+///             }

+///         };
+///         println!("{}", out);
+///     }
+///     Ok(())
+/// }
+/// ```
+///
+/// Implementing this parsing logic without `peek2(End)` is more clumsy because
+/// we'd need a parse stream actually advanced past the comma before being able
+/// to find out whether there is anything after it. It would look something
+/// like:
+///
+/// ```
+/// # use proc_macro2::TokenStream;
+/// # use syn::parse::{ParseStream, Result};
+/// # use syn::Token;
+/// #
+/// # fn parse(input: ParseStream) -> Result<()> {
+/// use syn::parse::discouraged::Speculative as _;
+///
+/// let ahead = input.fork();
+/// ahead.parse::<Option<Token![,]>>()?;
+/// let args = if ahead.is_empty() {
+///     input.advance_to(&ahead);
+///     TokenStream::new()
+/// } else {
+///     input.parse()?
+/// };
+/// # Ok(())
+/// # }
+/// ```
+///
+/// or:
+///
+/// ```
+/// # use proc_macro2::TokenStream;
+/// # use syn::parse::{ParseStream, Result};
+/// # use syn::Token;
+/// #
+/// # fn parse(input: ParseStream) -> Result<()> {
+/// use quote::ToTokens as _;
+///
+/// let comma: Option<Token![,]> = input.parse()?;
+/// let mut args = TokenStream::new();
+/// if !input.is_empty() {
+///     comma.to_tokens(&mut args);
+///     input.parse::<TokenStream>()?.to_tokens(&mut args);
