Scala has many libraries for new and refined types, but do you know the difference? 🤔 New types create distinct types (think new boxes for your data). Refined types add constraints to existing types (think labels & rules for what goes in the box). Artūras Šlajus just released a newtype library exclusively for Scala 3! #scala #typesafe

In my opinion, Scala should be moving towards a clearer, more unified syntax, as demonstrated by improvements to implicits and underscore usage. Introducing [] for collection literals, when those symbols are already fundamental to the type system, seems to me a violation of this principle. I believe it's a step backward, it adds unnecessary ambiguity to the syntax. #scala
