| Yeuph | hey I'm struggling with something | 00:10 | |
| this won't work | |||
| class IsEven { has $.num; method CheckEven { if ($.num % 2 = 0) {say 'Is Even';} else {say 'Is Odd';} } } | 00:11 | ||
| keep getting "Cannot modify immutable Int" | |||
| what bit of logic am I missing here? | |||

| rf | it should be == 0 | 01:16 | |
| not = 2 @Yeuph | |||
| not = 0** | |||
| Yeuph | yeah... | 01:17 | |
| I forgot this beams into the other text channel | |||
| I humiliatedly deleted my text hoping no one had seen it after I saw it lol | 01:18 | ||
| rf | Also for the first part, I'm fairly certain that doesn't work :) | ||
| Yeuph | lol | ||
| rf | Well, not as you think it works | ||
| Yeuph | I arrived there after 30 minutes of trying to figure out why my program wouldn't work | 01:19 | |
| and no, that doesn't work either lol | |||
| rf | m: say %(5, 2); | ||
| camelia | {5 => 2} | ||
| Yeuph | ya, looks like some functional thing | ||
| rf | It's actually a map. | 01:20 | |
| Yeuph | When I tried that I did get the program to work | ||
| except not how I wanted to | |||
| so I came in here asking what was going on because that didn't make sense to me either | |||
| rf | %(n, m) should always be truthy so it would always hit the truthy block | 01:21 | |
| m: say %(5, 2)<5>; | |||
| camelia | 2 | ||
| Yeuph | Thanks for chiming in. I'm gonna get back to my book. All of humanity was just killed, very exciting. I guess I'm rooting for the spiders now (Children of Time) | 01:22 | |
| rf | Haha, enjoy! | 01:23 | |

| Nemokosch | AlexDaniel mocked it 😩 | 07:54 | |
| el gatito (** advocate) | is a class object just an instance of the class itself | 08:15 | |
| m:perl class C {} say C.WHAT; | 08:19 | ||
| Raku eval | (C) | ||
| el gatito (** advocate) | the class of class C is C itself | ||
| mind blown | |||
| lizmat | yes | 09:00 | |
| el gatito (** advocate) | the reason why class methods are not separated from instance methods is because classes are just instances of itself | 09:09 | |
| so instance methods are applicable to class | 09:10 | ||
| Nemokosch | in Python land: "static method" = sub inside of class, "class method" = method invoked on a class instance, "object method" (does it even have a name) = method invoked on a concrete instance | 09:14 | |
| el gatito (** advocate) | object method is called instance method in python (and most otger languages as well) | 09:18 | |
| the class isn't even responsible for creating instances unlike python and ruby the metaobject is | 09:23 | ||
| Nemokosch | a class corresponds to a metaobject, for what it's worth | 09:24 | |
| one could say that the class is the syntactic representation while the metaobject is the (runtime) behavior | 09:27 | ||
| el gatito (** advocate) | meanwhile in python the class is the metaobject lol | 09:30 | |
| Nemokosch | that's a blessing and a curse at the same time | 09:38 | |
| more stable APIs -> safer and easier to work with BUT more burden on the implementations, therefore one needs to give up on own speed | 09:40 | ||

| nHail | Is there a way to turn a junction into a list? I saw iterator, but that seems too complicated | 19:05 | |

| Nemokosch | I think "officially" there isn't, de facto it's possible | 19:43 | |
