Apart open questions to related to https://bugs.python.org/issue39069, this PR looks good to me.
@isidentical: Are you interested to measure the overhead of functools/enum imports/code? See https://bugs.python.org/issue39069#msg358498

Yes but currently I can only reply through mail because bpo logins with
google doesnt work. And if needed I can implement this lazy loading idea i
proposed earlier.

Wait. I'm not sure about this one. Are you going to omit parenthesis here sometimes?
The change is correct, but direct write() calls are maybe better.

Same here, I'm not convince thta delimit() makes the code more readable.

@vstinner a general answer, I used delim in everywhere we are using brackets for the sake of consistency. If it looks better without them, I can just revert back in few places. |

@pablogsal: Do you prefer to only use delim() when parenthesis can be optional, or are you fine with replacing all write(x) ... write(y) with "with delim(xy): ..."?
I am fine with replacing all |

I am going to land this one to unblock the rest of the work. @vstinner, we can move the discussion about the readability of the code that you mention to the issue or another PR 😉 |
|
Thanks for the PR @isidentical! 🎉 |
|
|
I guess this is not related with my PR, does it? |
Is not, is a core dump on FreeBSD. This is going to be fun.... |
|
Thanks @isidentical and @pablogsal: the commit 4b3b122 is nice! I will to implement smarter parenthesis. @isidentical: ping me if you want a review on a "smarter parenthesis" PR, once you will have it written down (I didn't check if it's already the case). |
|
@pablogsal: "Is not, is a core dump on FreeBSD. This is going to be fun...." Did you open an issue to track this crash? |
Nop...I started vacation that day and I never did 😞 |
Yes I rebased it a top of this PR (and just fixed some conflicts due to other PR of mine), @vstinner. You can review |

Oh, it's the PR #17377, ok. |
