This looks cleaner but unfortunately it doesn't work right away. My code does not terminate anymore when I use this instead. I don't know why but I will investigate more.


Well done, @kklimek1! I appreciate you taking the time to correct your file extension. 💛


We're using `test` _way_ more often, and it's waaaayyy easier to `grep` for. `[` is a shitty name because it looks like syntax, when it's not.

So could you please leave these as they are?


From what I understand, there may be a difference in speed of movement.
