I understand a desire to keep it pure.  Would it be useful to add a
separate method to support non-Unicode access?  This style of access has
some wonderful properties in terms of decoupling, accessibility,
learnability, and uniformity.  I can image that many kinds of bulk
string operations could benefit from this interface:

t.transform('des_encode', key=0x10ab03b78495d2)
t.transform('substitution', name='guido', home='netherlands')
