Flash is not very good about their built-in objects behaving as objects.
Adam used to use something like this to test for an object being a
function:
if (x == null && (! x)) ...
So, functions are similar to null and false in a boolean context, so
this might be part of that old hack?

Some Flash8 built-in objects are too scary:
var id3 = audioplayer.getID3(); //audioplayer is a LzView
typeof id3; // 'object'
typeof id3.constructor; // 'undefined' -> aha, a built-in object
id3 == null; // true
id3 == undefined; // true
id3 != null; // false
id3 != undefined; // false
id3 === null; // false
id3 === undefined; // false
id3 !== null; // true
id3 !== undefined; // true
Finally: !!(audioplayer.getID3()); // true
Whatever their indention was....!?
