https://issues.dlang.org/show_bug.cgi?id=24653 Issue ID: 24653 Summary: Keyword ordering inconsistency of `auto ref` Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: qs.il.paperinik gmail.com For most, `auto ref` is a 2-token keyword, but at most places, it’s not required that `auto` and `ref` be in a particular order or next to each other. This is a valid function template declaration: ```d void f()(ref const auto int) { } ``` There’s one exception to this: Lambda returns. Lambdas require `auto ref` in this order. Either the latter should be relaxed or `auto ref` should be required in this order for all uses. While relaxing the lambdas would be the obvious non-breaking change, maybe insisting on `auto ref` is actually the desirable option. Probably very, very little code uses `ref auto` or something other than `auto ref` (considering `ref auto` has very few hits on the Forum). --
