alt Hacker NewsThe only issue I have with Scala 3 is Python envy, they should not have come up with a second syntax, and pushing it as the future.
If anything is slowly down Scala 3 is that, including the tooling ecosystem that needs to be updated to deal with it.

It's on brand for Scala to have multiple ways of achieving the same thing.
Now we x2 by having the curly brace syntax and the indent syntax.

You could also have compared it, more attractively, to Haskell.

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➕ show 3 replies
Everything is up to date with the new syntax as far as I'm aware. Also, the compiler and scalafmt can rewrite one to the other. A project can pick whatever style it wants and have CI reformat code to that style.
