Sorry. I did not realize that the maketrans function had not then been
moved from the string module to the str class object, unlike nearly all
other functions from string, including the translate function. I also
misremembered that maketrans did not have the new third delete param.
What I did do once long ago was something like
>>> import string
>>> a = 'abcde'.translate(string.maketrans('bd','**'))
which is not very nice.
