Dollar Sign ($) in ActionScript Identifiers? It's a No-no

Do you use $ in your ActionScript for class or member names? (I know I've seen it used sometimes in place of the underscore (_) for private members.) If you do, maybe you shouldn't.
I recently caught wind of this little paragraph in the ECMAScript language spec (section 7.6):
This came up as a result of some issues I was having sorting out class member definitions that did in fact use the dollar sign in their identifier names. Tisk tisk.
