Rust: Naming Cleanup and Rollup Season
A wave of renaming and clarity fixes moved through the compiler today, from splat's name change to predicate-to-clause cleanups, alongside two large rollups bundling dozens of smaller fixes. The overall pattern is maintainability work: making internal names, error messages, and code organization clearer without changing behavior.

Good morning. It's July 31st, and today's activity is dominated by one theme: naming things correctly, and cleaning up after past shortcuts.
The clearest example is the splat rename saga. PR 159817 renamed splat to avoid colliding with stable names, and a same-day follow-up, PR 160244, went further and renamed it to "rustc splat" specifically in error messages. That's two passes on the same problem in one day, which tells you the first fix didn't fully…
That same instinct shows up elsewhere. PR 160177 continued a "predicate to clause" renaming effort, cleaning up naming left over from an earlier refactor. PR 160223 renamed validate operand to validate place in the interpreter, fixing a name that stopped matching its own function signature "a long time ago," as the…
Second theme: parser and diagnostic precision. PR 160175 stopped over-recovering from bad const arg parses, since excessive recovery was producing cascades of irrelevant errors. PR 160234 shortened overly long type paths in missing-argument suggestions. And PR 160250 will label unstable trait items in suggestions so…
On process: two large rollups, PR 160238 and PR 160278, each folded in over a dozen smaller merges —…
