https://issues.dlang.org/show_bug.cgi?id=18280 Issue ID: 18280 Summary: std.algorithm.comparison.cmp for non-strings should call opCmp only once per item pair Product: D Version: D2 Hardware: All URL: http://dlang.org/ OS: All Status: NEW Severity: enhancement Priority: P3 Component: phobos Assignee: nobody@puremagic.com Reporter: n8sh.secondary@hotmail.com Right now when comparing non-string ranges std.algorithm.comparison.cmp calls the comparison predicate twice for every pair of elements to determine their order. When the elements have overloaded `opCmp` and the predicate is "a < b" we only need to call `opCmp` once for each pair. -- |
