w05: Fix exercise quizzes and improve solutions #566

Closed sadphi closed 3 years ago

sadphi commented 3 years ago

I just discovered that the quizzes in exercise w05 were reset to the version pre-migration, which was due to me incorrectly editing the generated .tex files in compendium/generated instead of quiz/QuizData.scala. This should be fixed in this PR, but I can't build the project as I currently have issues with Scala and sbt, so I haven't been able to check it myself. But according to the Github Actions run it should be fine. I also tried running sbt build on another PC that is running Windows, but the build failed there due to Windows missing the program tail.

Very good that you spotted this! However it seems as if some of the behaviour is not Scala 3 but Scala 2; have you tested this with Scala 3? For example MutablePt() should compile and new is not needed in Scala 3 etc. (For details on universal apply methods see https://docs.scala-lang.org/scala3/reference/other-new-features/creator-applications.html )

Let's discuss this live on Discord before further actions.

Let's move strict equality to in-depth exercises.

I've now moved the exercise on strict equality to the in-depth exercises, and revised it to just be about analysing the behaviour.
