Fancy strings in Scala 3

Our goal will be to create dedicated types for non-empty and lowercase strings. We’ll use opaque types and inlines, which are new features of the Scala 3 compiler.

Scala & the Three Implicits

After writing my three-part series on Options, Try and Either, which ended with the added bonus of explaining the elusive Monad, I’ve been wanting to write another series - again, aimed at the beginning-to-medium-level Scala programmer, that would inspire people to explore another cool and power aspect of Scala centered around Typeclasses and Implicits.
