For the `MiddleDot` case, current behaviour: - For a case like `1.2`, `sym1` is `1` and `sym2` is `2`, and `self.token` holds `1.2`. - It creates a new ident token from `sym1` that it puts into `self.token`. - Then it does `bump_with` with a new dot token, which moves the `sym1` token into `prev_token`. - Then it does `bump_with` with a new ident token from `sym2`, which moves the `dot` token into `prev_token` and discards the `sym1` token. - Then it does `bump`, which puts whatever is next into `self.token`, moves the `sym2` token into `prev_token`, and discards the `dot` token altogether. New behaviour: - Skips creating and inserting the `sym1` and dot tokens, because they are unnecessary. - This also demonstrates that the comment about `Spacing::Alone` is wrong -- that value is never used. That comment was added in #77250, and AFAICT it has always been incorrect. The commit also expands comments. I found this code hard to read previously, the examples in comments make it easier. |
