ilya-biryukov added a comment.
I did some experiments with adding something similar to the `ErrorExpr` Aaron suggest. It has this flag set and does not get removed from the AST.
I believe the best way to address Aaron's comments is to add tests mentioning this expression instead of trying to catch `TypoExpr`, which normally get removed from the AST.
Would need some time to fix a few remaining test failures (bogus diagnostics), I'll update this patch when I have something (hopefully tomorrow).
