If I recall correctly, the biggest feature that was dropped was developer-defined namespaces. I think AS4 just had public/private/protected/internal. So there would be no more mx_internal. > Not all features of AS4 can be implemented -- at least not easily and > efficiently -- on the existing Flash runtime. An example of something that couldn't be efficiently implemented on the existing runtime is the change of primitive types like "int" in AS4 to be defined as machine-like 32-bit integers that wrap around from 2147483647 to -2147483648 rather than converting to Number when they get large. You need new (faster and simpler!) opcodes for that. - Gordon -----Original Message----- From: Gordon Smith [mailto:gosm...@adobe.com] Sent: Wednesday, January 22, 2014 10:55 AM To: dev@flex.apache.org Subject: RE: ActionScript 4? What the hell? Adobe designed AS4 to be the language for a new Flash runtime ("V12") that it was working on but dropped. (I was working on the AS4 compiler then.) Not all features of AS4 can be implemented -- at least not easily and efficiently -- on the existing Flash runtime. However, some features can be. Alex, I suggest that you try to arrange for the donation of the incomplete AS4 compiler to Apache for cherry-picking. - Gordon -----Original Message----- From: Kessler CTR Mark J [mailto:mark.kessler....@usmc.mil] Sent: Wednesday, January 22, 2014 10:32 AM To: dev@flex.apache.org Subject: RE: ActionScript 4? What the hell? Well using the assumption that AS 4 would be an improvement in some area's from AS3 even if it was an incomplete work. While I haven't looked at it yet, I would be interested in just seeing the differences and bring over small pieces that could be an improvement for us. Assuming it wasn't in the same direction as ASC 2 which started getting rid of things we use. -Mark -----Original Message----- From: Alex Harui [mailto:aha...@adobe.com] Sent: Wednesday, January 22, 2014 12:20 PM To: dev@flex.apache.org Subject: Re: ActionScript 4? What the hell? I'm not sure what the rules are. The language reference is under Apache license. The specifications are under CC-NC which is not good. I suppose I could try to get that changed. But first, come up with something you do want to cherry pick that doesn't require implementation in the runtime. -Alex On 1/22/14 8:39 AM, "Kessler CTR Mark J" <mark.kessler....@usmc.mil> wrote: >Since this is hosted publicly but not donated, I assume we cannot >cherry pick any good changes from as4... > >-Mark > >-----Original Message----- >From: bkelley [mailto:brady.kel...@cleantelligent.com] >Sent: Wednesday, January 22, 2014 11:15 AM >To: dev@flex.apache.org >Subject: Re: ActionScript 4?
