Matt,
The only serious defense of exceptions I know of is that you can use them to
avoid the boilerplate you guys use heavily throughout your source
(CHKERRQ/SETERRQ). As long as you remain committed to the boilerplate, I
can't think of anything that exceptions grant you in C style code. As Barry
notes, they can be used to try and handle things in
constructors/destructors, but they are very dangerous in those methods and
only work when every data member can clean itself up (see:
