| - Binary and TASTy: No impact. End markers are purely syntactic sugar for braceless blocks and do not affect emitted bytecode or TASTy semantics. | ||
| - Source: Largely backward compatible. The only change is accepting additional `end <id>` and `end new` tokens where previously only a dedentation closed the block. Name-checked markers that do not match will report errors as they do today for definition end markers. | ||
| - Tooling: Formatters and IDEs may optionally insert or display these markers; existing code without markers remains valid. |
There was a problem hiding this comment.
Couple of examples:
- Metals (via SemanticDB) - references to method symbol to include the new end marker
- Presentation Compiler? if that also reports symbol occurrences in source files
