The only thing I can see in the demo code that you can't do in regular Python is the sequence literal. So `s"ACGT"` vs `Seq("ACGT")` or something. Oh, and having the Python 2 `print` instead of Python 3 `print()`.
Is there something else?
The marketing page claims to offer "up to a 160x" perf improvement to Python. No idea how though.
Numpy does that too, but it's a domain specific lib. I doubt they are speeding up real python itself.
