[boost] Upcoming formal review of the [Boost.]Yap library

Hi everyone, The formal review of Zach Laine's 'yap' expression template library will be starting in 3 weeks, from Feb 05 to Feb 14. yap is a C++14-and-later library to build expression templates, much like Boost.Proto currently does. yap uses new features introduced in C++14/17 to make the library simpler to use and compile faster than existing solutions. The documentation is available here: https://tzlaine.github.io/yap The official repository is here: https://github.com/tzlaine/yap We encourage folks to become familiar with the library and submit feedback to the author even before the review starts. Thanks! Louis Dionne (review manager for this submission)
