Review Comment:
   Good question. I was going to point to the stdlib, but apparently that's 
also inconsistent:
   - Iterator uses `_ == elem`: 
https://github.com/scala/scala/blob/v2.13.10/src/library/scala/collection/Iterator.scala#L449-L461
   - `Seq` uses `elem == _`: 
https://github.com/scala/scala/blob/v2.13.10/src/library/scala/collection/Seq.scala#L365
   
   Although I believe that `elem == _` makes more sense. ~~Otherwise it feels a 
bit useless to define `indexOf[B >: A]` 🤷~~ (Nevermind, it actually makes sense)
