Speaking strictly from a standards perspective, it seems that we are getting a bit ahead of ourselves. The $ properties of RegExp and the behavior of of setting them to reflect the most recent exec is not part of any edition of ECMA-262. It seems like they should be in Annex B, but apparently nobody has ever proposed that and/or offered a specification for them. Getting them into Annex B sounds like the first step. Since it is Annex B that defines them, Annex B could then also define a flag to eliminate them them. But then a program that asserted that it didn't want to use that Annex B feature would be dependent upon the presence of Annex B support. Annex B contains many changes to RegExp from the base standard. Perhaps a better way to approach this is to have a standard (not Annex B) regexp flag (perhaps 's', for "standard" or "strict") that means that this regexp should be strictly applied using only the ES standard semantics without any Annex B or other extensions.
