Boost hana with C++11 or alternative libraries

I would like to use Boost.hana, but I have read it requires C++14 while I can use C++11 only. Do you guys know it one of its previous versions used to be implemented with just C++11 so that I can use that? Any alternative ?

How about libraries that implement C++14 and c++17 features using C++11?

Thanks in advance
