Well my typical code looks more like
load(...) {
ifstream is("myfile");
binary_iarchive ia(is);
my_data d;
ia >> d;
return;
}
with the first try block "miles" away from the call. With a whole lot of
layers in between. Layers which may or may not invoke threads.
The use you don't see is that I can do this. By not using boost
exception you force me to take extra care either everywhere I use
serialization or everywhere I use threads.
Its not much work, but it still inhibits a much cleaner abstraction level.
