Hello everyone,
I wanted use the access operator ([]) for a normal list in Elixir, and I got an ArgumentError.
I look at the Access.ex and I realized that there is implementation for access just for keyword lists.
Why isn't there an implementation for a normal list too?

No, because the Access protocol is meant to be implemented by Dict like data structures and a list, generally speaking, is not a performant dictionary. The only exception is keyword lists which are meant to have at maximum a dozen keys!
