| Tirifto | I suppose hashes are not meant to be messed with while they’re being iterated over with ‘for’? | 19:13 | |
| librasteve | nss | ||
| Tirifto | ~~ not so simple ? :o | 19:14 | |
| librasteve | no shit sherlock | ||
| (sorry that was a bit harsh) | |||
| Tirifto | Ah, elementary it is. xP | 19:15 | |
| librasteve | XD | 19:16 | |
| or, as lizmat would say, doctor it hurts when I do that | |||
| nahita3882 | what's the reason &postcircumfix:<( )> is not accessible like this? | 19:18 | |
| works for {} and [] | |||
| Tirifto | (No harm done! c: I reckon this might be common sense, but I tend to imagine Raku as a hyperbolic land of endless possibilities, so I had to check. xP) | ||
| nahita3882 | m: &postcircumfix:<( )> | 19:19 | |
| Raku eval | Exit code: 1 ===SORRY!=== Error while compiling /home/glot/main.raku Undeclared routine: postcircumfix:<( )> used at line 1. Did you mean 'postcircumfix:<{ }>', 'postcircumfix:<[ ]>', 'postcircumfix:<[; ]>', 'postcircumfix:<{; }>'? | ||
| lizmat | nahita3882 possibly because postcircumfix ( ) is really a syntactic construct | ||
| although I don't see a reason why it couldn't exist | 19:20 | ||
| nahita3882 | i see thanks | 19:21 | |
| lizmat | m: sub postcircumfix:<( )>($callable, |c) { $callable(|c) }; &postcircumfix:<( )>({ say "foo: $_" }, 42) | 19:23 | |
| camelia | foo: 42 | 19:24 | |
| librasteve | Tirifto: you made me wonder whether other languages lock out the iterand - and whether raku (like perl) is deliberately relaxed since there may be certain self-referential code (aka footguns) that you could do (but would want to) | ||
| Tirifto | I don’t think I’ve tried, other than maybe Citrine, where I think it worked. `o` | 19:28 | |
| Assuming I want to iterate over some values (ordered or not), but might decide while iterating that I shan’t be needing to look at some of those values any more, is there a straightforward way for me to exclude those values from iteration? Or might I be better off recording such values in a SetHash (for example) and skipping them over as they come? | 19:35 | ||
| lizmat | there's "last" in loops ? | 19:47 | |
| Tirifto | Yes, but that always skips over all the remaining values, rather than only excluding a select few, no? | 19:49 | |
| lizmat | "next if $not-applicable" | 19:55 | |
| Tirifto | Very well! | 20:49 | |
