This summary might be used as a reference should the 'mutable
dictionary keys' issue come up again in c.l.py.
I had a look and I think you should correct the followingr:
  Dictionary lookup with mutable types like lists is a source of
  unpleasant surprises for the programmer and therefore impossible in
  Python.
Better, perhaps, to say:
  Dictionary lookup with mutable types like lists can be a
  source of unpleasant surprises for the programmer and
  therefore not recommended in Python.
It is not impossible in Python. It may be discouraged but it is not
impossible since I have already done so.
If I discouraged you from shooting yourself in the foot would you do 
that too?
