Scala 3 Comprehension Syntax

Finally a real reason to upgrade to Scala 3 for Wha!? For comprehension improvements are coming!!! 1. Starting for comprehensions with aliases: Current Syntax: val a = 1 for { b <- Some(2) c <- doSth(a) } yield b + c New Syntax: for { a = 1 b <- Some(2) c <- doSth(a) } yield b + c

A social media post celebrates Scala 3 introducing improved syntax for for-comprehensions with aliases. The joke is that this small syntax change is presented as the long-awaited real reason to upgrade, making it a reaction for Scala developers discussing language updates.
