Enum.into passing a non-empty list is deprecated

Enum.into passing a non-empty list is deprecated

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

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