| Nahita | DarthGandalf: hi, my original message was my @a = [[12, 3], [4, 5]]; @a.splice(1, 0, [@a[1].clone,]); @a[1][2]++; say @a; the essence of it is passing [@stuff,] with comma-trailed to splice. clone is so it's not shared, and ++ is to prove it's not shared | 08:00 | |
| trailing comma is needed because otherwise [...] calls .Array, on ... (even if it doesn't explicitly call it, the end effect is the same from what I have seen) | 08:06 | ||
| it's kind of surprising actually, i stumbled upon this recently: | |||
| m: [%(3, 4, 5, 6)].raku.say | 08:07 | ||
| Raku eval | ["3" => 4, "5" => 6] | ||
| Nahita | isn't a 1-length array with the Hash, rather the Hash is spread to its pairs | 08:08 | |
| therefore, like in the bare parens case with 1 elem in it ($thing,) where "," must be there, in square brackets, for predictability for amateurs like me, "," must be there as well unless other interpretation is specifically needed | 08:10 | ||
| DarthGandalf | ah, I see, thanks | 08:49 | |
| that's surprising :( | |||
| $@foo still should have worked though, as it doesn't use the [] syntax | 08:50 | ||

| lizmat | DarthGandalf: yeah, I think *that* is the bug | 09:22 | |
| DarthGandalf | lizmat: perhaps it would be good to have some warning about [@foo]? | 10:48 | |
| lizmat | in what way? | 10:50 | |
| DarthGandalf | like, a linter | 10:51 | |
| or compiler warning | |||
| I tried to use that syntax when trying to make it work, and a warning would advice to add , there | |||
| since [@foo] by itself is not very useful, trying to convert an array to an array | 10:52 | ||
| lizmat | I think in RakuAST we would be able to add a worry | 10:53 | |
| OTOH, [@a] is a valid way to create a clone of an array | 10:54 | ||
| nemokosch | Yeah this is design... "seemed like a good idea at first" | 11:06 | |
| Also means that wrapping is idempotent | |||
| [[$x]] and [$x] are the same | 11:07 | ||
