In Java, numbers are not boolean values, and if you try to use one as
such you'll get a compiler error.
I'm not saying that "NOT len(string)" is a no-no, just that I think
"len(string) EQ 0" is clearer and easier to understand. It's all
personal preference. If Sean's guidelines recommend the former,
that's totally fine with me. I'm not going to do it that way, but
that's my choice. You'll also see my code littered with
find("substr", myString) EQ 0 and the like.
