Voldenet I wouldn't count on side effects in .map 10:16
with .race in the iterator it could cause some serious confusion 10:18
m: my @a=[^120]; gather for @a { .say.take } 10:19

frost I think there is a bug in the REPL, `[0] > my @a=[^120]; @a.map(<-> $a { $a++ }); [1] > say @a[101]; say @a[102]`, the result is `"102\n102"` 11:14
Put them on one line fixs the problem 11:15
BTW, why dose `@a.map(<-> $a is rw { $a++ })` not change values of @a? when `<->` and `is rw` are together, the side effects disappear 11:19
lizmat that last thing feels like a bug 11:20

Voldenet for me it doesn't feel like a bug, it's exactly what I'd expect from .map with side-effects 13:20
which is pure nonsense 13:21
fwiw ` @a.map(<-> $a { $a++ }).eager` does an expected thing 13:22

Xliff How can I tell if a command executed via qqx<> completed successfully? 13:23
antononcube I think recently there was a discussion about "HummingBirds" performance "web service wise." Is there similar discussion and / or benchmarks about "Cro" ? 13:30
13:34 Wonner joined
Voldenet Xliff: there's no way, QX never does anything to the exit code github.com/rakudo/rakudo/blob/main...kumod#L245 13:36
m: say shell(<ls /blah>, :out :err).exitcode 13:40

tbrowder ref File::Zip what does the version you want have that the other one doesn't? are both authors still available? 17:05
i've used Archive::SimpleZip to good effect 17:07

ptc tbrowder: one is a dependency of Selenium::WebDriver and was written by the same author; that particular version of File::Zip uses `unzip` to extract archives whereas the other File::Zip uses `extract` IIRC. 20:17
tbrowder: I don't know if both authors are still available; it's sort of hard to tell :-/
tbrowder: either way, I wanted to get Selenium::WebDriver to work and for that I needed one particular File::Zip and it didn't seem possible 20:18
tbrowder: ugexe gave a great tip in his answer to my issue on GitHub and basically mentioned that `zef install File::Zip:ver<0>` would also do the trick (`*` gets treated as being effectively 0) and yes, that works :-) 20:19

librasteve frost: @a.map(<-> $a is rw { $a++ }) is nonsense due to side effects as voldenet pointed out - also <-> does the is rw for you, no need to say it twice 21:41
tellable6 librasteve, I'll pass your message to frost
