Sweet Little Idea

Hello, loves! Sweet little idea … I have one. Very small but I think it’ll make things just a bit nicer. We’ll see. I’ve been improving the code both in the last few articles and sometimes when you weren’t watching. If there has been a theme to the work, it has been to move responsibility for things to the places where they seem to fit better. Something something cohesion. I know—or used to know—all that theory, but these days I follow much simpler practices, removing duplication, observing Feature Envy and moving code to the class we’ve been fondling a bit too much, and so on.
