tbrowder howdy, question for experts: given an object '$s', is it possible to create Raku methods to return a single value using these two syntaxes: '$s<a>' and '$s[1;2]'? 12:43
to be clear, each method should return one value 12:45
the object is an array 12:46
rather the object has an array as one attribute 12:47
i'm thinking that if i define an operator like <> or [] inside the class it might work somehow magically if done properly...or with a role... 13:03
13:07 linkable6 left, evalable6 left 13:08 jjido left
tbrowder hm, '$s.<>' or '$s.[]'... 13:09
or '$s.cell<>' or '$s.cell[]' 13:10

m: sub postcircumfix:<{ }>(@container, **@key) { 42 }; my $s = []; $s<a>.say

Voldenet it ruins the operator in the process though 13:19
m: augment class Array { multi method AT-KEY(Array:D: $key) is raw { 42 } }; my $s = []; $s<a>.say; 13:30

[Coke] ... why is this not working locally? Weird.
*FACEPALM*. because I already have a script with this handy short name earlier in my PATH. You would think I had learned this lesson by now. 14:46

tonyo you don't really need the `but` in there, this'll work fine too 17:02
m: role X { multi method AT-KEY($k) { $k }; }; my $l = X.new; say $l<a>; say $l<b>;

tonyo the [X;Y] syntax would require some grammar 17:13

tellable6 tbrowder, I'll pass your message to lizmat
lizmat tbrowder: then add an AT-KEY method to it 17:41

tonyo AT-POS can be done in a similar way but requires a little more fanagling 18:11
tbrowder and lizmat 18:32
and tonyo
tonyo m: role X { multi method AT-KEY($k) { $k }; multi method AT-POS(X: Int:D \p) { "{p + 1}"; }; }; my $l = X.new; say $l<a>; say $l<b>; say $l[1, 2]; 18:35
camelia a
b
(2 3)
tonyo AT-POS is called twice in that pattern ^
