Is there an active C++ opensource project similar to loki?

Hi,

I want to keep learning C++ with an opensource project, but loki is not active.
So which project is good, similar to loki, focus on C++ programming and design pattern?

Thank you~

I haven't used Loki and I've only used Boost a little bit, but I think Boost might be similar to Loki.

What do you exactly mean? Do you want to use it or join the project?
