Python already implements let*; it's called "tuple unpacking":
Python 2.3.3 (#1, Mar 9 2004, 14:21:31)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1493)] on darwin

>>> x, x['abc'] = {}, 3
>>> print x
{'abc': 3}
>>> x, x['abc'], x['abc'][4] = {}, range(10), -9999
>>> print x
{'abc': [0, 1, 2, 3, -9999, 5, 6, 7, 8, 9]}
