Thanks, it's definitely work in progress.

You found a bug. I fixed in rev 47. Here is how you'd use it:

>>> from PyICU import *
>>> c=Collator.createInstance()
>>> ck=CollationKey()
>>> ck1=CollationKey()
>>> c.getCollationKey('a string', ck)
<PyICU_collator.CollationKey; proxy of C++ icu::CollationKey instance at 
<PyCObject object at 0xf308>>
>>> c.getCollationKey('another string', ck1)
<PyICU_collator.CollationKey; proxy of C++ icu::CollationKey instance at 
<PyCObject object at 0xf1e8>>
>>> ck.compareTo(ck1)
-1
>>> ck1.compareTo(ck)
1
>>>

The collation key instance returned from getCollationKey() is the one you 
passed in:

>>> ck1 is c.getCollationKey('another string', ck1)
True
