Is there any real reason why most progranming languages look more like the 3rd panel and not like the 1st panel? There’s gotta be a reason for all the nesting and indents that has nothing to do with readability since that shit makes it harder to read.

Because the 3rd panel looks better when you have dozens of physical properties to track. It also makes retrieval easier because you can get all the physical properties at once, instead of having to read every line.

For an example that small it doesn’t matter, but for something larger it could become a performance benefit.
