The statements in Uppgift 9 in the expressions exercise trigger the following warning in Scala v2.13.3:

warning: method + in class Int is deprecated (since 2.13.0): Adding a number and a String is deprecated. Use the string interpolation `s"$num$str"`

This confused some of my students that were unsure if they had to care about warnings. Seeing as lecture 1 is perhaps a bit early

Currently our forms are not showing the same errors messages, we should make sure the error messages returned by Django (if the form was not valid) are the same.

This will allow students to navigate the repo structure easily, without having to come back to the main repo each time.
