There's already BOOST_THROW_EXCEPTION to allow users some
degree of adaptability when throwing an exception
inside a Boost library:

http://www.boost.org/libs/exception/doc/BOOST_THROW_EXCEPTION.html

However, BOOST_THROW_EXCEPTION does not assume that
the function throwing can return more or less normally:
the user can only specify a termination procedure. Besides,
it's not clear to me what the degree is of adoption of
this macro in place of raw throw across Boost libraries.
