Comment (by nasonov):

 As you may guess, the return statement was added to supress a warning.

 Can you please discusss possible workarounds on boost-devel? I don't have
 time, sorry.

 Off the top of my head:

 template<class R, class E> R throw_exception_impl(E const & e)
 {
     throw_exception(e);

     // I expect a lot of workarounds around this place
     return R();
 }

 and then

 throw_exception_impl<Target>(bad_lexical_cast(typeid(Source),
 typeid(Target)));
