I'm convinced that propagating *unexpected* exceptions into the joining thread is totally wrong and insensible.
would you rather abort the application??
Absolutely. That said, feel free to catch anything/everything but please don't impose this silliness on me. The only problem with respect to threads/futures is that the dynamic context in which exceptions are thrown (in the "joinee" thread) is "detached" (in space and time) from the dynamic context that is supposed to "decide" (my means of try handler(s) or lack thereof) whether this or that exception is expected or unexpected. That leads to the conclusion that a typelist of expected (to be caught in the joinee thread and "re-rasied" in the joiner thread at join point) exceptions shall be specified at thread/future creation time. regards, alexander.
