The docs say passing a non-empty list as the collectable is deprecated
This is a common pattern in test fixtures:
Enum.into([a: 1, b: 2], %{b: 3})
which basically takes attrs and overwrites “defaults” in the map
The docs say consider using Keyword.merge(collectable, Enum.to_list(enumerable))
But how do I correctly merge list into a map like above? Because Keyword.merge/2 seems to merge only list into list, and Map.merge/2 only map into map. And I don’t think I should be converting list to a map before the merge.
Any hints, please?

The collectable is the second parameter, which should no longer be a non empty list. The first parameter can be any list.

the collectable is the second argument, not the first one. So you are good there.

It’s
into(enumerable, collectable)So my
collectableis the map%{b: 3}- so it’s a “non-empy map” rather than “non-empty list” and therefore the deprecation warning doesn’t apply?LostKobrakai
Exactly.

If you are not getting a warning, and your Elixir version is updated, it is because you are not doing anything wrong.
