You are talking about the use of generators as an array type, which I gather was the gist of your proposal in the propositions thread?
... I am looking forward to seeing your work on this, and the benchmarks on its performance. But I do not see how an implementation of that approach would be an adequate replacement for most of the optimizations documented on the http://code.jsoftware.com/wiki/Vocabulary/SpecialCombinations page. And you did say "The SC based system has has got to go". Note also: (*) in an interpreter time spent on code analysis is a cost to be minimized (though you can get away with more of this when working on large data sets and inefficient code than you can on small data sets and efficient code), and (*) the combinations chosen here were picked in part because they show up relatively frequently in real code, and in part because order of magnitude performance improvements were easy to implement.
