YAGNI is my secret Achilles heel :/
I'm always trying to read between the lines and anticipate the actual
requirements instead of what was explicitly asked. I've written and deleted
thousands of lines of code for this reason.

I know, they are technically constants.
But the semantics seem off to me... I can't really explain this properly. In
other languages, I would use `const` or `#define` (etc) to indicate a value
that will be used literally throughout the rest of the program. Any
reference to the constant can be replaced by its value. Declaring a `const`
only for the duration of a single loop iteration just doesn't seem "right".
