struct TokenCursor {
    tree_cursor: TokenTreeCursor,
    stack: Vec<(TokenTreeCursor, DelimSpan, DelimSpacing, Delimiter)>,
}
Expand description

Iterator over a TokenStream that produces Tokens. It’s a bit odd that we (a) lex tokens into a nice tree structure (TokenStream), and then (b) use this type to emit them as a linear sequence. But a linear sequence is what the parser expects, for the most part.
