No, but maybe you can replicate it some more :-)

I have seen worse effects of buggy code than this.   
Besides, in a PEP-308 world you would certainly find the like of

   self.stream.writeln("Ran %d test%s in %.3fs" %
                      (run, 's' if run==1 else '', timeTaken)

Getting things messed up with ternary ops (whichever) is easy enough.
That doesn't imply we have to introduce a new one.
