gfldex thinking about it, it should not just work but warn
TimToady well, do we ever want to allow an append with an option? 00:26
it kinda comes out to the unrecognized option on a method thing again
00:27 BenGoldberg joined
sena_kun We have a little warning about this in the docs. Perhaps it can be described as a "trap" on appropriate page. 00:27
gfldex %_ can be passed on when wrapping or assuming (if assuming would work on methods)
but I see little use for that outside of constructors 00:28
Hash is kind of a base class and wont pass anything on, at least in .append. So warning their would make sense.

gfldex i need to add a way to ignore methods that we don't want to doc 01:13
given I can implement that in Perl 6, that can't be hard. :)
sena_kun Actually, I plan to do a Big Review after we finish compileable examples work. I'm trying to do things a bit quickly here, but I saw some, um, really bad pages and I want to list them all(and learn the docs entirely, what an evil plan). It will be the next todo for me, I suppose. And caching. And offline version of docs. Okay, it's already 4 a.m. here, so I'm going to bed. Good night, #perl6! 01:17

sena_kun About the issues number... There are many pragma-related issues, many of "document this and that" issues, etc. There are not so many big and important issues like dead links and such, so we should be okay with it somehow. 01:20

terra's sorta a good thing, sorta very strange
it is embedded into lua code, and lua code uses 1-indexing... but terra uses 0-indexing, since it's closer to C for interop 05:14

kanl Supply . throttle returns a supply of promises. How does each promise correspond to the original items? e.g. my $s = Supply.from-list( |@a ).throttle: 3, -> $v { do-something-with( $a ) }; $s.tap: -> $v { how-to-figure-out-relation-here() } 07:01
this matters because when running a number of things in parallel, one supposedly would need to know whose promise got kept and whose got broken, not just which. 07:04
i don't suppose it's safe to stick things into a hash inside throttle's pointy block, not knowing it's act() or tap(), Someone care to share, please? 07:15

AlexDaniel TIL committing each rakudo build in a git repo, running ｢git gc｣ and then compressing the whole thing with something else results in better compression than when using almost anything else. But lrzip wins anyway. See github.com/perl6/whateverable/issues/23

22:17 trnh left
kyclark I’m going to be introducing my students to “gradual typing,” and I thought this might be a chance to show off enforcing “Int” on the arguments. It all comes down to the fact that “Slurpy positional parameters with type constraints are not supported.” OK. I’m still saved by the fact that “+” throws up on strings, e.g., 1 + “foo” 22:18
Thanks for all the suggestions!

unmatched} Does anyone want to do a good deed? pmurias++'s changes a few days ago removed koality from modules.perl6.org but the column in the db on the site is still there so now it's failing the NULL check on any new module added to the ecosystem. Someone needs to login to www.p6c.org and remove the dists.koality column in /home/modules.perl6.org/modules.perl6.org/modulesperl6.db 22:23
The easiest way is to just toss that file and let the site autogenerate the new and fixed version, but that kills the site for about an hour. Another easier way is to run the build process elsewhere and copy the file over :) 22:24
(I forget, but I don't think sqlite has a DROP COLUMN)

sena_kun We store our modules data in the sqlite base? Why not postgres or something(I mean, almost everything) better than this? 22:26
Also... storage3.static.itmages.com/i/16/08...e8ad3d.png - hyper operator "eats" list occasinally. Is it a known bug? 22:27
unmatched} sena_kun: I'm faling to see the betterment :) 22:28

sena_kun unmatched}, what about proper concurrency connections support? I can be too scared, because I had an accident with sqlite in the past, but still. Sqlite purpose is only testing/micro-examples.
