I am working on a branch that merges Pillow’s OleFileIO module in, and then finishes porting the remaining bits to Python 3. Coding and merging mostly done, but I should give it a bit of a test. At the moment the same code supports Python 2.7 and 3.2 as a minimum due to using @functools.total_ordering.
Would you be interested in such a beast? If necessary, it shouldn’t be hard to extend back to supporting Python 2.6 with the same code.
