you know that the list at the end is totally redundant, stop testing your readers.

Of course, the good old magic number. Much easier to remember everything when it’s always three.

With regard to the first half of the post, I tend to just remember one item in short term memory: an integer specifying the length of the list. One int is easy to remember, and it provides a sanity check when later calling up the contents of the list via associative memory.

Just… wow. Fucking brilliance.
