| antononcube | I know I can use <A B>.any in code like sq 'C' eq <A B>.any . But what is the point / how can I use the expression any("A", "B") . | 15:12 | |
| librasteve | Junctions are largely intended to be used in logical operations | 15:18 | |
| - I mean in the logical test part | |||
| antononcube | ok, and how is any('A', 'B') is used in those? | 15:23 | |
| nahita3882 | any("A", "B") is the same as ("A", "B").any is the same as "A" | "B" (also is the same as any(("A", "B"))) | 15:32 | |
| there is a subroutine any which calls .any on its invocant (and its signature is +values, so last one is the same for that reason) | 15:33 | ||
| github.com/rakudo/rakudo/blob/cee2...kumod#L487 | 15:35 | ||
| antononcube | Thanks1 | ||
| librasteve | m: sub fn($x) {if <A B>.any eq $x {say 'ok'}}; say fn:<A>; say fn<C>; | 15:49 | |
| Raku eval | Exit code: 1 ===SORRY!=== Error while compiling /home/glot/main.raku Undeclared routine: fn:<A> used at line 1 | ||
| librasteve | m: sub fn($x) {if <A B>.any eq $x {say 'ok'}}; say fn <A>; say fn <C>; | ||
| Raku eval | ok True () | ||
| librasteve | hopfully you get the idea | 15:50 | |

| .ohnowendigo | I really value that experts like @antononcube are willing to ask questions about parts of Raku they don't fully understand. It's a really big and complex language | 17:06 | |
| antononcube | I do not consider myself an expert in Raku -- I use it 70% of the time, but it is the slowest language I program with. Mostly because of my implicit assumptions about Raku based on too much programming with LISP-like languages. | 17:09 | |
