How to tell if an exception has been caught ( from inside the exception )?

[Dan]

If the exception isn't caught, it is printed to standard error. This
means that either __str__ or __repr__ is called (to convert it to a
displayable string). If the exception is caught, those methods
*probably* won't be called.
