Let’s look at a real example. Here’s the source code for binary search from rust’s standard library:

https://doc.rust-lang.org/src/core/slice/mod.rs.html#2786-28...

The function is pretty short - 40 lines including comments. Despite how short the function is, it still uses whitespace to separate and group adjacent lines of code. Personally, I find the code more readable like this. Indentation makes syntactic blocks obvious (the while loop and if statement). But there are also conceptual groupings between lines that mean nothing to the compiler, but are semantically meaningful to humans. I can tell at a glance that the comment about safety is most associated with that one line below the comment. And so on.

I think this code would be worse if we deleted the whitespace. How would you improve this code?
