| Summer | actually scratch that | 00:01 | |
| how to do the following: $potentially-nil.?Str | |||
| as in "stringify if defined, else nil" | |||
| .defined ?? .Str !! Nil given $potentially-nil; I guess | 00:04 | ||
| Kaiepi | my $potentially-nil andthen .Str | 00:27 | |
| technically, (my $potentially-nil andthen .Str) || Nil | |||
| er | 00:28 | ||
| my $potentially-nil andthen .Str orelse Nil | |||
| Summer | `git blame whoever-did-nil's-str-method` :sob: | 00:29 | |

| Kaiepi | m: put (my $potentially-nil andthen .Str) | 00:50 | |
| camelia | |||
| Kaiepi | m: dd (my $potentially-nil andthen .Str) | 00:51 | |
| camelia | Empty | ||
| Kaiepi | an empty list coerces to an empty string | ||
| Summer | it was going into a pair, but then I found out empty pairs are just still pairs | 00:54 | |
| but then i solved everything | |||
| method AT-KEY( $key where { NIC.parse: $_ } ) { | |||
| &!constructor( | $/.hash>>.Str ); | |||
| }; | |||

| Anton Antonov | I want to specify Whatever or Nil as values for CLI arguments. Right now make those arguments of type Str and check are the given values in <Whatever Nil>. Is there are a better or more concise approach? | 19:22 | |
| lizmat | multi MAIN("Whatever") { } multi MAIN("Nil") { } ?? | 19:34 | |
| Anton Antonov | @lizmat Yes, that works for me. I use(d) it. I was thinking something like MAIN( Str :$arg1 = v1, :$arg2 = Whatever where * ~~ Str || * ∈ (Whatever Nil), Num :$arg = 12) | 19:38 | |

| Nemokosch | How do I `take` a list by elements? | 21:36 | |
| `.take for @list` definitely works, is there something better? | 21:38 | ||
| Morfent | m:``` | 21:59 | |
| dd gather for <1 2 3>, <4 5 6> { take |@^xs } | |||
| ``` | |||
| Nemokosch | yes, this doesn't seem to actually flatten.. | 22:07 | |
