I tend to use a dictionary where all values are None for sets.
The STL does have some nice features which are missing from Python. For
example, C++ sets and maps are automatically sorted. However, I feel that
it would be easier to write a Python extension that provides these features
from scratch than to write a wrapper for the STL.
