I think maybe we're not disagreeing about anything at all. I wasn't arguing that splitting up the `case' is better -- I actually prefer the version that has one single `case'. My point was just that some of the earlier versions which did a repeated "am I supposed to be falling through?" conditional seemed like they'd generate worse code, and that it should at least in theory be possible to generate unconditional jumps with the straight-line tail-calling code.
That's been my thinking as well. I wasn't clear when I said "multiple tests" before.
