do we have any prior art of built-in functions doing something different when all parameters are undefined? like, not just default values for certain undefined parameters, but a special overload for the nullary case

i think some intl methods do funky things

You mean like Date()?

^ this was what immediately came to mind for me too

not counting the case of a required parameter being omitted, I guess?

If someone wants to pick up standardizing all the edge cases of the Date constructor, I think that'd be a very important project.
17:20
<jmdyck>
Which edge cases haven't been standardized?
17:20
<littledan>
all the non-ISO8601 ones!
17:20
<littledan>
this is a major point of compatibility issues between JS implementations
17:21
<jmdyck>
Ah, so Date.parse really.
17:21
<littledan>
it will be challenging to find the right set of things to interpret in practice to be compatible enough, but browsers have expressed appetite to upgrade to something if it's web-compatible in practice

hi! in test262 we have an RFC open (our first, as a trial of a new RFC process) about adding some facilities to test262 for improving the experience of writing asynchronous tests. we'd love to have some feedback from the perspective of implementers maintaining a test262 runner, and from (potential) test writers.

Does anyone know if https://fosstodon.org/@TC39 is a legitimate account (as in run by Ecma or a delegate)?
22:22
<linusg>
(I'd assume it's the same people as https://twitter.com/TC39 but I don't know about that one either :))
22:23
<nicolo-ribaudo>
It's legitimate, it's run by our chairs!
22:23
<linusg>
great, thanks!

<ryzokuken (back friday)>
I'd been meaning to add verified links to the TC39.es website or something but couldn't find the time yet
22:38
<nicolo-ribaudo>
It would be cool if there was already a PR open in the website repo waiting for review!
22:39
<nicolo-ribaudo>
It would have also been cool if the author of that PR realized that prettier was failing

re Date.parse, that was already attempted, and was blocked (by the chrome team as i recall)
