Hello, Please do not remove OldException. -Iavor Can you give any rationale? Are you trying to maintain compatibility with base-3 by using CPP + OldException? Is that significantly easier

1. I would have to go and change all code that uses exceptions, again. 2. I am not sure how to write backwards compatible code. CPP + OldException is not pretty but it works. 3. The extensible exception package is not Haskell 98 (it uses existentials), so it really would be nice if _it_ was placed in a separate package.

On that topic, it would be great if we had a way to see what are all the extensions used by a program (including those used by dependent packages).
