| nahita3882 | maybe the intention with * is that it is used with "quick" stuff and ternary isn't covered | 18:22 | |
| librasteve | m: say (5, 4)[4 ≥ 3 ?? 1 !! 0] | ||
| Raku eval | 4 | ||
| librasteve | m: say (5, 4)[2 ≥ 3 ?? 1 !! 0] | ||
| Raku eval | 5 | ||
| nahita3882 | like *.attr, * <infix> sth, *[idx] etc. all works but ternary is too much? idk the details | ||
| librasteve | m: (5, 4)[*.say] | 18:23 | |
| Raku eval | 2 | ||
| librasteve | (5, 4)[(* ≥ 3).say] | ||
| m: (5, 4)[(* ≥ 3).say] | |||
| Raku eval | False | ||
| librasteve | looks like ternary is a bug to me | ||
| m: say (5, 4)[4 ≥ 3 ?? *-1 !! 0] | 18:24 | ||
| Raku eval | 4 | ||
| librasteve | seems to be limited to use of * in the test of a ternary within an [] index | 18:25 | |
| if you agree I can log as a bug | |||
| nahita3882 | it doesn't work in [] but it doesn't work outside either | 18:26 | |
| not working in the sense that it doesn't produce a closure | |||
| but instead evaluates to what the truthful part of the ternary gives immediately | |||
| because the whatevercode is truthful | |||
| like any other sub | 18:27 | ||
| perl In [25]: (* > 3 ?? 2 !! -1).WHAT (Int) | |||
| user (like Time Melon and probably us too) expects this to be still WhateverCode | |||
| maybe a bug, maybe some technical detail (like ternary shortcircuiting), so it's up to you to file the bug but thanks if you take the time of course | 18:29 | ||
| maybe shortcircuting is the thing: | 18:30 | ||
| perl In [30]: (* >= 2) && 7 7 In [31]: (* >= 2) & 7 WhateverCode.new | |||
| perl In [32]: ((* >= 2) & 7).(55) all(True, 7) In [33]: ((* >= 2) & 7).(-55) all(False, 7) | 18:31 | ||
| i.e., with the all-junction, it did produce a closure, which we can call | 18:32 | ||
| with the && logical-and (which shorcircuits), no closure yes direct evaluation | |||
| timemelon | ohh I see, the whatever code just doesn't include the ternary | 20:21 | |
| funky, I wonder if there's a list of what is and isn't included anywhere | 20:22 | ||
| docs don't mention ternaries anywhere so idk | 20:27 | ||
| thank you for letting me know why it wasn't working! | |||

| nahita3882 | np | 07:07 | |
| there is a table in that link but it says when it stays as a Whatever object, the ternary et al.'s situation is different | |||
| and indeed not documented there; maybe we can document the shorcircuting operators' behaviour with regards to * there | 07:08 | ||
| somewhat unrelatedly: is it only me or others can also see unused and unnecessary scrollbars in the code snippets in the documentation's website | 07:10 | ||
| e.g., | 07:11 | ||
| cdn.discordapp.com/attachments/768...ce3c2& | |||
| both horizontal and vertical | |||
| maybe i should ask in the raku-doc channel | |||
| lizmat | and yet another Rakudo Weekly News hits the Net: rakudoweekly.blog/2024/10/07/2024-41-knowlite/ | 16:52 | |

| librasteve | maybe it’s * as in Inf? | 04:41 | |
| vendethiel | lizmat++ # all great proposals/tickets | 14:11 | |
| "Final" methods with no *%_ are very interesting | 14:12 | ||
| ab5tract | timemelon: I'm not sure why the docs don't include it but there is indeed a list in the Rakudo source | 17:42 | |
| github.com/rakudo/rakudo/blob/19a3...kumod#L312 | 17:43 | ||
| lizmat | hmmm isn't that already part of OperatorProperties ? | 17:48 | |
| if not, it probably should | |||
| timemelon | interesting! I don't see ?? on there, does it desugar to && somewhere along the line before this code? | 18:00 | |
| ab5tract | timemelon: it's rather that it is not even considered for being "curried": github.com/rakudo/rakudo/blob/7d08...umod#L2895 | 18:33 | |
| it would need to have `is WhateverApplicable` there for that to be the case | |||
| I don't think that ternaries are a good fit for being primed, though | 18:34 | ||
