Fair call.

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 :-)
