Not really. Sometimes, for example at a 'C' API boundary, you simply have to
use catch(...) so you can prevent an exception from crashing your caller.
Tom Becker has already pointed that out. And, as I've pointed out, when
well-used, the type of an exception doesn't tell you much about what's
needed for recovery - only how to report the error - and there are some
processes for which continuing to run is much more important than an
accurate error report.
