boost::int128 review starts today (July 22 - July 31)

Announced officially on the [Boost mailing list](https://lists.boost.org/archives/list/boost@lists.boost.org/thread/GLZALH3WRHSICP6ZYOFDOPWUQTJUKOM5/)

**Introduction**

The formal review of Matt Borland's `boost::int128` for inclusion in the Boost libraries, starts today.

Int128 is a portable C++14 implementation of signed and unsigned 128-bit integers. It has no dependencies, is header-only, and can be consumed as a module in C++20. It serves as a practical solution to the partial (resp. absent) support of 128-bit integers by gcc/clang (resp. msvc), and as a lightweight alternative to heavier projects.

You can find the library and its documentation here:

Although possibly not faithful to Matt's implementation, this CE link will be handy if you are in a rush but want to play with the library.

Anyone is welcome to post a review and/or take part in subsequent discussions in the mailing list.
