Ahhh, thanks! ;-) Just for the record: import StringIO class MyStringIO(StringIO, object): pass must of course be: class MyStringIO(StringIO.StringIO, object): pass One more question - is it likely that StringIO will be turned into new-style class in the future? The reason I ask is whether I should try to deal with detection of new-/old-style classes or take the old-styleness for granted and set in stone instead.
