[Laszlo-dev] Flash built-in objects

[P T Withington]

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?
