The motivation here is to eliminate the `Option<(Delimiter, DelimSpan)>`, which is `None` for the outermost token stream and `Some` for all other token streams. We are already treating the innermost frame specially -- this is the `frame` vs `stack` distinction in `TokenCursor`. We can push that further so that `frame` only contains the cursor, and `stack` elements contain the delimiters for their children. When we are in the outermost token stream `stack` is empty, so there are no stored delimiters, which is what we want because the outermost token stream *has* no delimiters. This change also shrinks `TokenCursor`, which shrinks `Parser` and `LazyAttrTokenStreamImpl`, which is nice. |
