I like the idea of mandating lexicals vars. This would also eliminate the need for spilling (I think), as the register allocator would only need to refetch the lexical rather than save it off somewhere to be restored later. I get the feeling that this is equivalent to requiring exception handlers to be a locally defined closure, which is another way we could go about this.
