Because I'm used to `case v; when 1,2,3` it feels like `case v; in 1,2,3` should have a similar meaning. So it's possible to omit the square brackets but honestly I don't see much point for that, it just makes it look to me like something it is not. In other words, I feel it would be far more intuitive (at least to me) if ```ruby case v in 1,2,3 ``` was a synonym for ```ruby case v in 1 in 2 in 3 ``` or possibly a synonym for ```ruby case v in (1|2|3) ``` which would make it similar to the syntax in `rescue A, B, C => err` Is it too late to change this? -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
