FIOC exception classes

Which approach do you prefer:

1. Create new exceptions for each class of error in your libs.

2. Just use stuff from the exceptions module most of the time and create new exceptions when using a standard one is really inappropriate.

My colleagues strongly prefer #1, and go around making dozens of FilePermissionsError or ValueErrorBecauseFuckYou.  They are also OOP and Patterns nuts.  I am not a very happy man because I have to import their horde of bullshit exceptions into my modules instead of just using standard classes.

Matching text in error messages when handling errors?  Even Perl programmers don't do that.

You have transcended my preconceptions of Ruby user unprofessionalism with your code example.
