Yes, this is both more expressive and at the same time probably even 
more efficient.


Question though:

 >>> u'abc'.translate({u'a': u'A'})
u'abc'

I would call this a chance to improve Python. According to the 
documentation, using a string is invalid, but it neither raises an 
exception nor does it do the obvious and accept single-character strings 
as keys.


Thoughts?
