soundex breaks deepcopy somehow

running Soundex on a string changes the original string to uppercase.
That's all well and good, but interestingly, it also changes a deep copy of the original string! that seems pretty wrong...

#!python

>>>x = "blabla"
>>>y = copy.deepcopy(x)
>>>sndex = fuzzy.soundex(32)
>>>print sndex(x)
B4140000000000000000000000000000
>>>print x
BLABLA
>>>print y
BLABLA
>>>#running soundex on x changes deep copy y!

This fork has got it fixed : https://bitbucket.org/dhellmann/fuzzy
Basically deepcopy doesn't work because strings are immutable in python but since the library internally makes a C call, it gets modified in place by C which should have not happened.
