Agreed on all points, but when the deadline is approaching and the code
needs to be done...
Ironically to your points, I'm relatively new to Flash (~2 months), and have
come to this language from C, C++, and Java. It's been *far* more difficult
to learn than I expected, in many cases due to the "hacks" you mentioned.
("Whaddya' mean 'this' doesn't refer to the class instance when you're in a
callback function _that's_a_method_of_the_class_!?!")
That said, I'm a pragmatist when it comes to finishing a project. :-]

Subject: Re: [Flashcoders] Singleton in AS3
That's fine for use Flashers who are used to using such methods to get what
we want.
However, other languages are more strict, and from the perception of new
programmers coming into ActionScript 3, not meeting their expectations is a
failure of the language... to point. Bottom line, they see our "methods" as
"hacks", and that's a bad thing.
The correct way is to use getInstance, yes. But, it should also throw an
exception if you try to instantiate it:
var a:MyClass = new MyClass();
That should not work, but it does currently because you have no choice.
In an effort to make ActionScript more clean, strict, and helpful, this is
one of the additions. The language itself should be self-explanatory to use
it, and should support common programming patterns such as Singleton.
Supporting design patterns in a language, to me is iffy, but there are a
enough business use cases in my opinion to support it.

Why should a public constructor prevent the creation of a Singleton? All
you need is a static getInstance() method and a private attribute to hold
the created instance. Sure, the public constructor means someone else could
instantiate the class on their own without using getInstance(), but if
you're writing the code, you'll do it the proper way anyhow, no?

You can't yet as for the reason you stated. Bitch on the forums pretty
please; you, many many others, and I all want this changed.

Hi guys,
Have anyone got ideas how to implement Singleton pattern in AS3 best?
Constructor in AS3 can only be public or internal, which is not private
anyway. ..
