A quick test shows the error message to be very specific in this case, 
where as the *something error message requests a more general sequence.


 >>> def foo(**b): pass

 >>> class a: pass
...
 >>> foo(**a)
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: foo() argument after ** must be a dictionary
