Thank you for sharing the library. I only had a look at the documentation
(which is really high standard) to try to determine the difference between
LEAF and Boost.Outcome. It is my understanding that the main difference is
that LEAF allows heap-free type erasure of error-related data at the
expense of exploiting thread-local storage. Is this a fair summary?
