GenericDiffReporter __init__ takes a tuple - quite annoying

[objarni]

I think the GenericDiffReporter should just take two arguments, not a tuple. Saves a lot of dev.time worldwide :)

Update: It would be possible to be backwards-compatible by using the *arguments syntax, and then go different paths depending on the length of that list:

 if len(arguments) == 1:
    # Old code here
 else:
    # New code here

.. but I'm not sure it's worth the hassle.
