TokenStream holds a `tt::Subtree` but assumes its `delimiter` is always `None`. In particular, the iterator implementation iterates over the inner `token_trees` and ignores the `delimiter`. However, `TokenStream::from_str` violated this assumption when the input consists of a single Group by producing a Subtree with an outer delimiter, which was ignored as seen by a procedural macro. In this case, wrap an extra level of Subtree around it. Fixes #7810 Fixes #7875 |
