No, I haven't looked at them. Python 2 has them since release 2.6, so it's out of my reach for any practical purpose at the moment (I need to preserve compatibility with Python 2.4). > A typical rule of thumb in Python land is that heterogeneous data probably belongs in a tuple, so practice goes a little further than immutable lists. The problem with Python tuples is it's two things mixed: immutable lists and a container for heterogenous data. It's the same situation as JavaScript's objects.
