It seems to be working. Can you elaborate on what’s missing?

FYI you can make it return a Boolean rather than an Option[Unit]. Then at use site just write case CollectionSet() =>

This is incomplete since, it's blocked by scalameta/scalameta#1212 (Add support to query type of a term) iset: immutable.Set[Int] cset: collecion.Set[Int] both have +/- implemented via SetLike given iset + 1 cset + 1 we know that + is from SetLike, but it's not possible to get the type of iset/cset Rewrite collection.Set.+ restrict type of lhs scalafix allow us to match on SetLike.+ but we cannot check the type of the expression on the lhs We can work arround this limitation if the lhs is a identifier (simple case). This allow us to document the expected type on the lhs and prepare the implementation once scalameta/scalameta#1212 is resolved

Can you also add the following test case?
- imap + (2 -> 3) + ((4, 5))
+ imap + (2 -> 3) + ((4, 5))
