In fairness, when I ported the Bash version to PowerShell and then Python, the Bash version was much shorter. rasengan later added a lot of functionality to the Bash version.
And the point was to demonstrate some of the functionality in a short example, not to be a line-by-line port. I find it's easier to learn a new language by looking at a short example. The rest is left as an exercise to the reader.
