The series introduces explicit keyword-flavored indexing (`[try: i]`, `[build: i]`, `[panic: i]`) to replace the previous implicit syntax (`[i]`, `[i]?`), and adds a new panicking index projection variant. The motivation is sound: the old syntax was ambiguous about what kind of bounds checking was happening, and having a panicking variant fills a real gap for cases where the compiler can't prove bounds but the programmer knows the index is valid. The series follows a clean progression: rename, refactor, add new feature, convert callers, remove old syntax. The series already has Reviewed-by tags from Alice Ryhl, Andreas Hindborg, and Alexandre Courbot on several patches, which is a good sign. The code is generally clean and correct. One substantive concern is in the `index()` implementation for `Range` which uses `unwrap_unchecked()` after bounds checking via a ZST slice -- this is correct but the split between the check and the unsafe call creates a subtle correctness dependency. A minor documentation nit exists in the cover letter. Overall: **Looks good.** The API change is a clear improvement in readability and safety. --- --- Generated by Claude Code Patch Reviewer
