Summary: "replace" function should accept lists.
Initial Comment:
It would be nice if the "replace" function accepted lists/
tuples and replaced each item in the "old" list with the
corresponding item in the "new" list.

I'm -1 on complicating str.replace()'s API for functionality
that substantially duplicates that offered by str.translate():
>>> "Hello world".translate(string.maketrans('ed', 'ae'))
'Hallo worle'

Hmm, actually I was requesting that string.replace() accepted
lists of substitutions, like so:
>>> "Hello world".replace(["e", "d"], ["a", "e"])
'Hallo worle'
But your suggestion would also be very useful.

Are you requesting that lists be given a replace() method
that parallels the replace() method for strings?
def replace(self, old, new):
result = []
for elem in self:
if elem == old:
result.append(new)
else:
result.append(elem)
self[:] = result
