Last week it was brought to my attention that there are currently 5
different libraries and proposals for dealing with the problem of reporting
errors from noexcept functions, so I thought it would be useful to update
the Noexcept documentation with a short section comparing all the different
designs: https://zajo.github.io/boost-noexcept/#alternatives.
