This gets to intent.

What, in the code base, does char_a mean? Is it append_command? Is it used in a..z for all lowercase? Maybe an all_lowercase is needed instead.

I know that it's an "A". I don't know why that matters to the codebase. Now, there are cases where it is obvious to even beginners, and I'm fine with it as magic characters, but I've seen cases where people were confused to why 1000 was in a `for(int i = 0; i<1000; i++)`. Is 1000 arbitrary in that case, or is it based on a defunct business requirement in 2008? Will it break if we change it to 5000 because our computers are faster now?
