Yes, this jumped out at me too. The whole point of Boost.Exception is to 
carry arbitrary data along with the exception, so an example that uses 
Boost.Exception instead of the custom 'traced' type should be given.

This sounds like a pretty good idea, although I'm not sure if we can enable 
it by default as people have historically been very sensitive to changes to 
BOOST_THROW_EXCEPTION. But an opt-in macro should be fine and very useful as 
one would automatically get stack traces from every use of 
BOOST_THROW_EXCEPTION. Hello Java.
