As a lurker watching this debate with interest I just had an idea out of the
blue idea that may or may not have value but might reduce the desire to create
a new exception type Exception type for every error.
What if the catch syntax was extended to take both a type and a condition.
try {
write(filename, ...);
}
catch(FileException e; e.errno == EEXIST) {
}
catch(FileException e; e.errno == EROFS) {
}
I realize that this is just syntactic sugar for catch(...) { if(...) {}} feel
free to shoot it down.
