yep, str(35.72) == '35.72'. As I use d() only on literals, and will
carefully avoid it if I should ever enter more than six digits in such a
literal, _in practice_ (as I said) I find it works well, whether _in
theory_ it's arguably wrong or not. Were it a built-in I'd no doubt
have different feelings, but as a handy user-coded one-liner it's fine.
