Is it an oversight that exception instances do no longer support
slicing in Python 2.5?

This code works in 2.4, but no longer in 2.5:

try:
open("", "r")
except IOError, details:

print details[:]

Technically, yes. There is no entry in the sq_slice field for the PySequenceMethods struct. Although you can get to the list of arguments by going through the 'args' attribute if you need a quick fix.

I have a fix in my checkout that I will check into the trunk shortly and into 25-maint as soon as Anthony unfreezes it.
