Access.find/1 and Access.filter/1

[Zach Daniel]

Some utilities that I often wish I had are `Access.filter/1` and `Access.find/1`. Often I find myself doing something like

list_of_results = get_in(some_list, [:path_a, :path_b])

filtered_results = Enum.filter(list_of_results, &some_predicate/1)

get_in(filtered_results, [Access.all(), :a, :b])

The PR w/ documentation and information can be found here: https://github.com/elixir-lang/elixir/pull/6634

Let me know what you guys think!

Apologies for using the informal "you guys", I sometimes forget that it is not an inclusive identifier. To anyone reading, use something like "you folks" or "everyone". :)

This is great! I've written a similar helper before to pick a single map out of a list of maps that matches a desired {key, val}

Yeah, it seemed like pretty common behavior in my projects as well. Now it is merged, so we should see it in 1.6! :)
