https://issues.dlang.org/show_bug.cgi?id=17032 Issue ID: 17032 Summary: Sortedness of a range should be propagated Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: greeenify gmail.com Since https://github.com/dlang/phobos/pull/4907, find has a specialization for SortedRange, however if another range function was applied before (e.g. `take`) the check won't work. It's probably possible to check the type and see if there's a SortedRange occuring. If so a simple solution would be to iterate towards it and check whether the struct on the way have a `propagatesSortedness` property. However this of course won't work for something like `retro`. --
