An implementation _could_ add a mode (*shudder*) along the same lines as strict mode: "die in hell ASI, i hate you with the fiery passion of a thousand burning suns.";
And then make it a syntax error whenever ASI would occur. I have considered this in JSC (albeit with a slightly shorter opt in string). It wouldn't have the backwards compat problems you get by "disabling ASI" as the points where ASI being removed changes behaviour would be errors :D --Oliver On Apr 17, 2011, at 4:24 PM, Garrett Smith wrote: > On 4/17/11, Allen Wirfs-Brock <[email protected]> wrote: >> >> On Apr 17, 2011, at 12:33 PM, Mike Ratcliffe wrote: >> >>> ... >>> >>> Personally I would welcome some kind of option to disable ASI with open >>> arms.
