>While elegant, the convention of cons cells as lists is increasingly going to be a flaw, because using linear recursion to process a list often obscures parallelism I disagree that it's a flaw. I think the problem here is this idea that we can only have one data type. For me, the main thing C++ got right was the STL. It didn't have one collection type, it had several. Each with its own set of trade offs. That's what we need in Lisp. You want instant insert but don't care as much about traversal? List. Fast random index-based access? Vector. And so on.
