CIAvash atweiden_air--: `AB` does not have the `$!a` attribute, `AA` does, so it can access it via `$.a`. You can do at least three things: 1. make `$.a is rw`, and in AB do `$.a =False`. 2. move `TWEAK` method inside `AA`. 3. Avoid inheritance and do `class AB does B does A { method TWEAK { $!a = false } }`. 06:38
atweiden_air--: But I think it's best not to use prompt in attributes, and leave it inside `TWEAK`: `role R {has $.a; has $.b; method TWEAK { self!prompt_a; self!prompt_b; }; method !prompt_a { $!a = prompt 'a (Str): ' }; method !prompt_b { $!b = prompt 'b (Str): ' } }; class A does R {}; A.new.raku.say;` 06:39
atweiden_air--: or if you want to override things: `role R {has $.a; has $.b; method TWEAK { self!prompt_a; self!prompt_b; }; method !prompt_a { $!a = prompt 'a (Str): ' }; method !prompt_b { $!b = prompt 'b (Str): ' } }; class A does R { method TWEAK { self!prompt_b } }; A.new.raku.say;` 06:41

lizmat .tell Xliff please, if you notice any changes, please make an issue. A workaround is nice, but if we don't know about issues, they continue to exist :-( 08:12

phil1 Hello, I am trying to translate Dough Hoyte's football-game macro (cf. Let Over Lambda, p. 77), to Raku. 09:10
Here's my first attempt.
Uploaded file: uploads.kiwiirc.com/files/b48d7dc3...pasted.txt
When I run it, I get this message: "expecting any of: argument list" 09:12
Sorry, my uploaded file doesn't containt "use experimental :macros;". 09:13
Are macros within macros allowed in Raku? 09:14
And here's the original Lisp code: 09:15

phil1 Hello, I found a solution without macros. 09:26

Please ignore my question.

Manifest0 Hi! 13:41
When we define a main function like "sub MAIN(Int $v)" shouldn't the type constraint be enforced when we invoke from the command line (in this example, shouldnt $v be Int and not IntStr)?
lizmat m: dd IntStr ~~ Int 13:42
camelia Bool::True
lizmat that's why an Int is also ok
Manifest0 m: dd IntStr ~~ Str 13:43
camelia Bool::True
Manifest0 This is problematic if i'm passing them to a new multi function 13:44
13:45 silasfox left
Manifest0 example: 13:47
Ambiguous call to 'sqlite3_bind(DBDish::SQLite::Native::STMT, Int, IntStr)'; these signatures all match:
(DBDish::SQLite::Native::STMT $stmt, Int $n, Int:D $i)
(DBDish::SQLite::Native::STMT $stmt, Int $n, Str:D $d)
(DBDish::SQLite::Native::STMT $stmt, Int $n, Real:D $d) 13:48
