Wrong syntax or a worksheets issue?
Hello, I've been getting strange errors while doing the exercise sheet 3. Trying to check with the correction, I'm still getting thee same errors. Is there something wrong with the worksheets and is there a way to fix this? Problem is, my code seems to compile, yet this error message shows up when I try writing "trait Tree[T]:" and iif i don't up the ":" other. errors appear.
