According to the docs lambda can handle the same parameter list as can
def. But this does not appear to be the case as the following (both
2.5.1 and 30a3) shows:

>>> def f(*a, **kw): return a, kw

>>> f(1,2,a=3,b=4)
((1, 2), {'a': 3, 'b': 4})
>>> A = lambda *a: a
>>> A(1,2)
(1, 2)
>>> K = lambda **k: k
>>> K(a=1,b=2)
{'a': 1, 'b': 2}
>>> X = lambda *a, **k: a, k
Traceback (most recent call last):
  File "<pyshell#17>", line 1, in <module>
    X = lambda *a, **k: a, k
NameError: name 'k' is not defined

So either this is an interpreter bug, or a doc bug.
