| * **Map** operations `map`, `flatMap`, and `collect`, which produce a new collection by applying some function to collection elements. | |||
| * **Conversions** `toArray`, `toList`, `toIterable`, `toSeq`, `toIndexedSeq`, `toStream`, `toSet`, `toMap`, which turn an `Iterable` collection into something more specific.

I'm sorry it took me so long to reply. It's true, as you point out, not all of the to(collection.X) generates a copy. |

thank you! |
