ELLIPSIS and RARROW are missing in EXACT_TOKEN_TYPES. Patch attached.

This looks good to me.  A few questions.

The patch is fixing an obvious bug, but there could be code that
depends on the current broken behavior (the table has been incorrect
since Python 3.3).  How do we feel about such breaking changes?
I am OK with this one.

Will you add tests?
msg246693 - (view) Author: Stefan Krah (skrah) * (Python committer) Date: 2015-07-13 17:04
I think with the ASYNC/AWAIT changes any code using
will have to be updated anyway in 3.5 and in 3.7 (when ASYNC/AWAIT
will finally be real keywords).

So this is probably an ideal time for the change.  I'll add tests.

We obviously missed this, at least for 3.5... any chance of having it for 3.7?

Stefan, do you have time to make a PR for this?
msg289613 - (view) Author: Stefan Krah (skrah) * (Python committer) Date: 2017-03-14 17:46
Not right now, but if anyone makes a PR I can click the merge button. :)

Thanks for the PR! -- Merged.

I would suggest adding this to the what's new document The change affects user-facing code (the exact_type attribute of TokenInfo is OP for ... and -> tokens prior to this patch). 

I would also point out that this directly contradicts the documentation (from, "To simplify token stream handling, all operator and delimiter tokens and Ellipsis are returned using the generic OP token type. The exact type can be determined by checking the exact_type property on the named tuple returned from tokenize.tokenize()."), so I don't see why it can't be backported.

I would not mind backporting this. Let's think about it for a while.

The 3.6.6rc is next Monday.  3.6.8 will be the last 3.6 maintenance release.
msg319103 - (view) Author: Stefan Krah (skrah) * (Python committer) Date: 2018-06-08 20:08
Yikes, I wasn't aware that we are that late in the 3.6 release cycle.

Perhaps it would be unusual to change it now, even though it is a bug fix.

What do others think?

+1 for adding a mention in the 3.7 What's New doc (anyone willing to produce a PR for (master Doc/whatsnew/3.7.rst ?)

-1 for backporting to 3.6.  Since 3.6 has been out there so long and is nearing the end of its maintenance life, it seems to me to not be a good idea to make a change like this that is more likely to break existing code than to fix something that a small number of 3.6 users may have been waiting for.
msg319107 - (view) Author: Stefan Krah (skrah) * (Python committer) Date: 2018-06-08 20:55
I agree, it would be strange to backport now.
msg375830 - (view) Author: Guido van Rossum (gvanrossum) * (Python committer) Date: 2020-08-23 23:23
Closing, this is out of date. EXACT_TOKEN_TYPES has been moved to in 3.8 and is now automatically generated from Grammar/Tokens. 3.7 is too old to fix.
