Re: Do you use an exception class in your Perl programs? Why or why not?

in reply to Do you use an exception class in your Perl programs? Why or why not?

I sometimes use exception objects because catching exceptions based on class is less fragile than catching exceptions based on examining the error message.


if ($@) {
    # Fragile.
    if ($@ =~ /My error message/) { ... }
    else { die $@ }

    # Robust.
    if (blessed($@) and $@->isa("MyError")) { ... }
    else { die $@ }
}
