Square brackets would be semantically dependent if they appeared in the same position of angle brackets. There's nothing magical about [] that makes the problems with <> disappear.
- GoblinSlayer 11mo agoIt disappears the problem that angle brackets are sometimes not brackets. I.e. a<b>c is parsed as (a<b)>c or as (a(<b>))c.
- xscott 11mo agoIt also comes up when you want compile time expressions as parameters to your generics: // nice and clean let a = Generic[T, A > B]::new(); // gross curlies needed because of poor choices let a = Generic::<T, {A > B}>::new();
