That’s the type of suggestion it will probably never be able to give. The existing suggestions just iterate through all variables or all function names and compare what you wrote in your code with what’s available. So it’s a simple similarity check of strings.
List.join should be
Enum.join on the other hand requires a whole lot of extra knowledge about elixir – even knowing that
List might correspond to
Enum in the first place. As most Enum functions return lists it does fit quite well as suggestion for
List, but what about other modules of enumerable types like
Map.map/2 I’d expect different behaviour as
Enum.map, as it should return a map not a list. The proper suggestion would imho rather be
Map,new/2, which takes an enumerable (so also a map), maps over it and returns a map. Or e.g.
Tuple.filter/2: Even though there’s a Enum function of that name filterering doesn’t make very much sense for tuples, which are meant to be fixed-size containers of data. Even
List.group_by doesn’t fit
Enum.group_by very well, as it’s one of the few
Enum functions not to return a list, but a map of data.
