I&#39;m trying to use the new (for me at least) extensible exceptions and<br>I am little amazed that I cannot get catch, try or mapException to work<br>without telling them which exceptions I want to catch. <br>What is the rationale behind this?<br>

How does bracket manage to catch all exceptions?<br>What should onException do?<br>Is there some example code that uses these exceptions, or better documentation?<br>Thanks in advance,<br>Immanuel<br>
