| As a former Scala fan, wow you aren't kidding, wth val month = i match
case 1 => "January"
case 2 => "February"
// more months here ...
case 11 => "November"
case 12 => "December"
case _ => "Invalid month" // the default, catch-all
// used for a side effect:
i match
case 1 | 3 | 5 | 7 | 9 => println("odd")
case 2 | 4 | 6 | 8 | 10 => println("even")
// a function written with 'match':
def isTrueInPerl(a: Matchable): Boolean = a match
case false | 0 | "" => false
case _ => true

| It's been a while since I touched Scala but wasn't that a thing in previous versions, minus the braces not being present? |
| |
| ▲ | weego a day ago | parent [-] | | Yes, that's all just as it was, and in places braces were not required / interchangeable so this is more of an optional compiler choice than a real change |

| Sorry, I'm coming from C++-ish background - can anyone explain what's going on :) |

| ▲ | hocuspocus a day ago | parent [-] | | Scala 2's syntax is mostly Java/C-style with a few peculiarities. Scala 3's optionally allows indentation based, brace-less syntax. Much closer to the ML family or Python, depending on how you look at it. It does indeed look better, but brings its share of issues.[1] Worse, a lot of people in the community, whether they like it or not, think this was an unnecessary distraction on top of the challenges for the entire ecosystem (libraries, tooling, ...) after Scala 3.0 was released. - [1] https://alexn.org/blog/2025/10/26/scala-3-no-indent/ | | |
