That's quite a speed-up, isn't it? It looks like the newly optimised version of 6to5 effectively inlines the tail call, similar to the way a real compiler would, and so avoids function call overheads altogether. Smart move. I hadn't realised the processing done by transpilers like 6to5 was so sophisticated, and I have even more respect for their developers now than I already did.
