contributors.scala-lang.org has become my favorite website this past week. It’s very interesting to read through the debates about new language features for Scala 3 (Dotty). For instance, in the Make concrete classes final by default discussion I think everyone agrees they wish they had gone that way with Scala 2, but it would cause too many problems if they tried to make this a new standard in Scala 3. The discussion — in addition to reading Effective Java — makes me wish I had used
final before all of my classes.
In another discussion titled, Why does Scala need its own build tool (SBT), someone makes a claim that Martin Odersky and his team created SBT as a build tool solution, and Mr. Odersky replies, “Definitely not my answer. I was always very skeptical of SBT’s approach and remain so.”
