Fair call.
For miscellaneous errors, you can use one the standard exception classes, such as runtime_error, using a stringstream to format the results, if you like:
stringstream s; s << "somebody made " << x << " mistakes"; throw runtime_error(s.str());
This gives you the results you want, doesn't it? Is it really that inconvenient?
Oh, well I'm alright, because I'll go on using my streamy exception where I think it's warranted. Convenience is an interesting question though. To some extent (no offence to the authors of excellent libraries that I use a lot and am extremely grateful for) my use of boost::lambda and boost::bind amounts to avoiding the inconvenience of hand writing function objects - but I wouldn't want to live without them. Funny that gcc's runtime_error uses a string copy constructor that could potentially throw :-) cheers, Geoff
