For most normal uses you just need to provide a sort key, but more complicated cases can get more complicated. I tried very hard to make everything easy, but I'd also be curious if others can come up with better ways of doing the interface.

I am not an expert on Boost.Sort and only had a quick look at your changes, but:

If I understood correctly, your new algorithm increases the requirement for Boost.Sort to C++17 from C++11. I don't see a good reason for doing that. You can replace if constexpr and the generic lambdas in your implementation with other code constructs that work on C++11.

Regarding the interface, shouldn't it follow the example of spreadsort?

Regarding having an extra single-header version: that seems overkill to me. Boost.Sort already claims to have no dependencies on other Boost libraries and is header-only, which should make it extremely easy to include in any project.

"These algorithms do not use any other library or utility. The parallel algorithms need a C++11 compliant compiler."
