I’m not sure how to respond to that. Fwiw this quote from docs might be helpful:
The Enumerable protocol is useful to take values out of a collection. In order to support a wide range of values, the functions provided by the Enumerable protocol do not keep shape. For example, passing a map to Enum.map/2 always returns a list.
This design is intentional. Enumerable was designed to support infinite collections, resources and other structures with fixed shape. For example, it doesn’t make sense to insert values into a Range, as it has a fixed shape where only the range limits and step are stored.
The Collectable module was designed to fill the gap left by the Enumerable protocol.
