Issue ID: 16282 Summary: Partial permutation/nextPermutation in std.algorithm Product: D Version: D2 Hardware: All URL: http://dlang.org/library/std/algorithm/sorting.html OS: All Status: NEW Severity: enhancement Priority: P3 Component: phobos Assignee: nob...@puremagic.com Reporter: wyatt....@gmail.com It'd be nice to have a way to set k for n!/(n - k)! std.algorithm.sorting.nextPermutation gives unique permutations (which is nice), but it modifies in-place and returns a boolean. (Also, why is it in sorting?) std.algorithm.iteration.permutations actually returns the permutations, but doesn't look for uniqueness AND has no other settings. --
