AFAIK: This is C++11-only, and while the API is basically lifted from
Boost, the Boost solution for C++03 is not fully general (IIRC only
works with exceptions derived from something-or-other); doing it with
full generality for all possible types of exceptions is only possible
with the C++11 extension.
