This paragraph is probably best turned into bullets at this point -- the four sentences are fairly independent of each other, and the transition from "per-argument function comments" to "parse has been augmented" is particularly abrupt.

Done reading. Looks good! I have a number of comments above, but I think they are all small, and I think the only one that affects the behavior is about a syntax-error case. |
Python 2 per-argument type comments are now converted into Python 3 annotations.

Huh, will this work if there are no type comments -- do we end up with an empty sequence for n.type_comments, or None?

It's an empty sequence.

Hmm, it looks like the "d" is on the wrong side of these backticks. A pre-existing nit.

Ooh, let me fix that.

Finished reading through the new version -- just a couple of comments which are all on documentation. (I wish I knew a reasonable way to get GitHub to tell me what the recent comments were.) |

Is this aligned funny, or is GitHub displaying it in a surprising way?

The file uses tabs. Fixed
