+1 on what Fred said (i.e. post-moratorium, add a keyword-only "key" argument to KeyError, set "e.key" only if that argument is supplied, update the standard library to supply it and use a default message of "'Key not found: %r' % key" if the key argument is supplied without an explicit message). Also +1 for doing the equivalent with AttributeError and an "attr" keyword only argument.

Keyword-only arguments are rather annoying to use from C code, though.
