I've posted a patch removing tuple parameters as #1678060.

There was one case in itertools tests/docs where IMO readability was  
lost:

->>> for k, g in groupby(enumerate(data), lambda (i,x):i-x):
+>>> for k, g in groupby(enumerate(data), lambda t:t[0]-t[1]):
...     print(map(operator.itemgetter(1), g))

Is it OK to replace this with:

 >>> for k, g in groupby(data, lambda i, c=count(): c.next()-i):
...   print(list(g))
...
