Thanks Karl for the excellent links on Alchemy optimizations! Man this stuff is fiddly. If Adobe could just make their AS VM run as fast as the C# one, devs wouldn't need to jump through these hoops!
BTW, does anyone know whether is Alchemy still "pre-release"? The Alchemy page at Adobe Labs... http://labs.adobe.com/technologies/alchem ...has this warning/disclaimer: "The Alchemy preview is prerelease software that is not supported by Adobe and may contain bugs. It is therefore advised that Alchemy not be used to generate code for use in production." I vaguely remember seeing that disclaimer a year (or two?) ago. I wonder whether it's worth putting effort into learning the ins and outs of a technology that's not officially supported and into which Adobe appears to be putting few resources. -Gerry On 2011-07-20 , at 12:17 , Karl DeSaulniers wrote: > Hi Gerry, > Alchemy optimizations.
