Correct, Elixir rarely adds aliases, because it adds to the learning curve (and Enum is already a large module) and it also eventually becomes a struggle for consistency (this code base must “only use select” or “only use filter”).
Plus I personally dislike select because it partially conflicts with SQL, where it may read as filtering columns from a table but it is also as a mechanism to perform transformations akin to map. I believe some programming languages do provide a select with the same meaning as map, so it would add to the confusion.
