Hi! Suppose I have a test.fla with a document class associated, say DocTestClass.as.

Normally I load the test.swf and DocTestClass is automatically instantiated.

But I’m curious. What if I make some other instances of DocTestClass, with pure code, without loading the swf? What are the implications or possibilities?

In fact these questions in turn come from another original question: is it meaningful to make a document class a singleton? Or a document class (as I suspect…) cannot be instantiated more than once and so it’s implicitly a singleton?
