Cool! That's so far the clearest solution. An additional bonus is that except statements look nicer:
except: # still catches all Exceptions, just like except Exception:
except Error: # is what you normally should do
+1 on the general idea, I just don't specifically like that "except:" is the "wrong" thing to do: part of the PEP352 idea was that people writing "except:" out of ignorance would still not cause their program to intercept KeyboardInterrupt, or StopIteration.
Unless this new proposal also includes changing the meaning of "except:" to "except Error". Also, under this new proposal, we could even remove Exception from the builtins namespace in Py3k. It's almost always wrong to use it, and if you really really need it, it's spelled exceptions.Exception.
