Firstly, I think you're taking this waaaayyyy more seriously than it was intended. Secondly double foo = 1.2; printf(foo); puts(foo); won't compile, while double foo = 1.2; display(foo); works fine. Incidentally I actually think display is the only thing on this list that is probably worth using, you could also probably extend it to accept multiple arguments relatively simply as well.
