| ab5tract | m: role R { method m {…} }; my $r = R.new but role :: { method m { “m!” } } | 16:02 | |
| camelia | Method 'm' must be implemented by R because it is required by roles: R. in block <unit> at <tmp> line 1 |
||
| ab5tract | It would be kind of nice if the above worked, right? | 16:03 | |
| m: role R { method m {…} }; my $r = (R does role :: { method m { “M!” } }).new; $r.m.say | 16:04 | ||
| camelia | Cannot use 'does' operator on a type object R. in block <unit> at <tmp> line 1 |
||
| ab5tract | Shouldn’t `R.new but role` compose the role before calling `.new`? What if that new role has methods that influence object construction? | 16:06 | |
| I guess the answer would be “create a dedicated class for it, it’s not that hard" | 16:08 | ||
| But still, it seems a bit surprising to me | |||
| this is also annoying | 18:15 | ||
| m: role R { has $.a is required; }; class C does R { submethod TWEAK { $!a = “foo” } }.new | 18:16 | ||
| camelia | The attribute '$!a' is required, but you did not provide a value for it. in block <unit> at <tmp> line 1 |
||
| ab5tract | Feels like we could do the required check after TWEAK, instead of before it? | 18:17 | |
