When making the changes to remove backticks in eb2f70fdbf32, the _PyParser_TokenNames table was incorrectly updated. Now the indexes into _PyParser_TokenNames don't match the token numbers. This can be seen in the output of 'python -d': $ echo '2 << 1' | ./python -d	grep Token ... Token NUMBER/'2' ... It's a token we know Token RIGHTSHIFT/'<<' ... It's a token we know Token NUMBER/'1' ... It's a token we know Token NEWLINE/'' ... It's a token we know Token NEWLINE/'' ... It's a token we know Token ENDMARKER/'' ... It's a token we know The fix is trivial. Patch attached.

Is there a reason not to renumber token.h?

> Is there a reason not to renumber token.h? I thought about that, but at the time I wasn't sure whether or not that would break anything. I went with the current patch because it is lower risk. On the other hand, proper clients of token.h should only be using the macros and should have no knowledge of the numeric codes. If they do use the numeric codes directly somehow, then that is their issue. So, I guess it is OK to renumber token.h.

Here is a patch that renumber the tokens. I also regenerated token.py.
