Going to try it out now, but one thing really struck me in the announcement: "We'll change stuff without thinking about what it might break, and we won't even keep track of the changes." Is that really wise? What's wrong with doing a simple changelog with every modification? Since you'd expect only experienced programmers to be using Arc, you don't have to hold our hand explaining the implications of the changes - but making us diff the source would probably be a bit much. I mean it doesn't have to be verbose even. Or even tidy. This would be better than nothing: * Added a global weak reference hash map to treat any object like a hash using {} syntax, ie, (= {someobj hashindexobj} 5). * Hash idea sucked. Removed.
