The Python version of ST is a very close port of the Java version.
This makes it much easier for me to keep the implementation correct
(as in 'like the reference implementation') - at the price of often
suboptimal, un-pythonic solutions.
I haven't spent time on optimizing it yet, I did not even ran it
through the profiler, so I can't say if there are big and/or easy
opportunities for improvements.
