That is really weird, huh?
Well, for strings, I think it's often better to use .length for Boolean
tests, anyway:
function test(s:String) {
if (s.length) {
// Catches any nonempty string.
} else {
// Catches null, undefined, and empty strings.
}
}

Thats very strange, but in usual case you do not check for the pure
value, but for the value, saved in a variable:
a = "foo";
trace(!a); // false
