Type Alias TokenIter

pub type TokenIter<'a> = ShadowCountedIter<'a, <TokenStream as IntoIterator>::IntoIter>;

Type alias for the iterator type we use for parsing. This Iterator is Clone and produces &TokenTree. The shadow counter counts tokens in the background to track progress which is used to keep the error that made the most progress in disjunctive parsers.
