Aaah, thats learning in my pace. Thanks, underrated video, underrated language.

16:00 Where I last worked, it was very important to use the size_t in our C code, and generally _t variants. I'm still learning low level programming, but I think it was to do with it being embedded software having to run on many different platforms. I also couldn't use bool because we had a few platforms (or compilers for those platforms I guess) that didn't support this type.

In your example where number:u8 = 254

You can, as shown in video, "roll over boundary":
number +% 10 // number is 8

But you can also use so called "sentinel" to "stop at (higher or lower) boundary":
number +| 10 // number is 255 which is the max for u8
