We’ve had an ING Scala Meetup last night.

In the first half of the meetup, Ayush Mittal did a live presentation on the newly introduced types of Scala 3 — enums, intersection types, untagged union types.

In the second half of the meetup, I did a live coding session on implementing Type Classes in Scala 3, and what this major version of the compiler brings new to the table for helping us to encode type classes — presentation starts from beginner level but then progresses to advanced 😅
