You should look at some of the discussions in the comp.lang.c++.moderated
archive :-) You'll find that opinions about that vary widely.
The fact is, with properly implemented exception-handling code that *does*
care about runtime overhead, you can write much faster code by using EH for
flow control than by the traditional "if (foo) bar(); else baz();" method.
Typical applications that come to mind are complicated recursive-descent
parsers (one of the examples in c.l.c++.m was a MIDI interpreter).
Besides, you can use lean-and-mean EH for "exceptional events only" designs
quite easily...
