We'd be far better off getting something as an answer - even if it is imperfect. Maybe its hopeless? Is it a little too much like asking "What's the best kind of car to drive?" or "What's the best shotgun to have?" - Too many potential uses and personal preferences to come up with a "best" answer and nobody wants to settle for a sub-optimal answer. Maybe we'd end up with Lists and Maps if the next standard just has them show up in a sneak attack, but it seems that this process is not likely to get a consensus strong enough to get a result. I think that Ted proposed a package that would make a good start. But that rather quickly shot off in a few dozen directions with objections on all sorts of fronts - and it was only one little lonely list package. I could still imagine taking it pretty much "as is" and adding to it a map package that looked similar and declaring that "Version 1.0". Any chance that proposal would gain any support? Anybody else have a proposed answer? I think if we don't commit to some direction pretty soon, the stagnation and deadlock will result in a lack of interest and this will wither on the vine. Too bad. Its a good idea and a noble goal.
